Photo cache size

I have about 1800 pictures which i resized and stuck in a folder to sync, they are about 100mb total, but when I sync them to my iPod with iTunes it creates a cache folder that is 1.3gb. Why is it so large and can I turn off the cache folder?
Thank you.

I just bought a new 15" PowerBook (hi-res) and iPod with Video. I've synched my entire 4 GB photo library to the iPod at the optimized resolution. I have almost 5000 photos in my library according to iPhoto.
My photos are almost all 1600x1200, usually about 800k, but between 500k and 1 meg in size, depending on compression. From what I can tell, the "optimized for iPod" images really shouldn't be any larger than 300k (320 x 240 x 32 bit color depth) even if they're totally uncompressed. At most, my iPod Photo Cache should be about 3/8ths the size of my iPhoto Library, or in this case 1.5 GB.
My iPod Photo Cache folder within my iPhoto Library is a little over double the size of my entire iPhoto Library, or 8.2 GB! When iTunes was synching the images, it indicated that twice the number of photos were being synched to the iPod, almost 10000! I can confirm from looking at images on the iPod that photos are indeed duplicates, so it seems the thumbnails from iPhoto have also been converted to iPod format. This is highly ineffecient; is there some way around this?
I can only assume that those who are experiencing this problem have chosen to put their entire iPhoto library onto their iPods instead of just limited albums; I'd assumed that when one chooses individual albums on the iPod that the thumbnails are not included since Albums exist essentially as aliases to the photos.
Since I've endured the lengthy conversion, I'm unwilling at this point to delete everything and experiment just to figure out exactly what's going on, but hopefully this provides some insight into what might be the source of the bloat in the "iPod Photo Cache"
Thanks for listening,

Photo Cache on iTunes

My photo directory is 12.9Mb.
When itunes syncs it creates a directory: iPod Photo Cache size: 410Mb.
When I try to sync with 500Mb free space on my ipod, there is not enough space to put all the photos on the drive.
Why does itunes inflate the files so excessively when 'optimizing' them? This is surely a example of bad programming by Apple. Anyone care explain this further or had similar problems like this?

Those photos taken or bumped photos should bi in the iPod's Camera Roll album
- If they are in an iPod backup then restore from that backup. Note however, that the the backup that had the photos may have been overwritten by a subsequent backup that did hot have the photos on the iPod.See the restore topic of:
iOS: How to back up
- If you used PhotoStream then try getting them from your PhotoStream. See that topic of:
iOS: Importing personal photos and videos from iOS devices to your computer
- Have you looked on the computer? Maybe they were imported to the computer and then deleted from the iPod. Since the photos were not synced to the iPod they are not in the iPod Photo Cache folder .

Why does iTunes use an iPod Photo Cache at all?

Hi,
When iTunes is used to synchronize photos to a device, it creates an "iPod Photo Cache" folder. Why does this folder even exist?
For users that have multiple devices with multiple resolutions (e.g., iPad 3rd Generation, iPad Mini, iPhone 4S, iPhone 3G), the iPod Photo Cache is grow to approximately four times the original size of the photo. If I have 15 GBs of photos and a 250 GB hard drive, then the combined usage of 75 GBs (15 GB photos + 60 GB cache) is extremely unreasonble.
Device resolutions change often enough (these days) such that having multiple devices is probably more common than having more than one of a single product. iTunes should be designed to do the real-time conversion (which it already does), but not save it to the hard drive.
Also allowing the ability to change the location of the "iPod Photo Cache" folder would help many users, but not myself since I do not have an external drive.
Any help is appreciated.
Thanks.

Thank you for your response. I should have clarified. When trying to delete from the library, it gives me the option to delete them from the computer or just from the library. I choose not to delete them from the computer, just the library. As a result, I would not expect the deletions to free up room on the hard drive, but I don't see how it actually increases the space used up on the hard drive. If I delete a song from the library, but not the computer, does iTunes save the song again someplace else (such that there are now two copies of the song somewhere on the system)? That seems to be the only explanation for why the free space on my hard drive would decrease after deleting a song from the library.

Purpose of folder "Ipod Photo Cache"?

What is the purpose of this folder? Should it be deleted automatically by iTunes after syncing? I've seen several posts here suggesting to delete the folder to try to resolve photo syncing issues. A co-worker tells me that this folder on his machine contains 2GB of .ithmb files. That seems to be a lot of space used unnecessarily.
Thanks,
Jack

No, it isn't/shouldn't be automatically deleted. When photos are synced to an iPhone (or iPod), iTunes creates an 'optimized' version of the picture (all the files are of uniform disk size and pixel resolution) and those are stored in the iPod Photo Cache. You can recover that space if you need to, especially if you put a lot of photos on the device that you later removed (by unchecking those albums, for example). If you delete the cache, iTunes will re-create the optimized versions at the next sync (for all the pics on the device).
http://support.apple.com/kb/TS1314
@DaVBMan, as to why it's large, regardless of their original size, 'optimized' pics take up the same amount of space in the cache, for a given device.
Note that this means if you sync the same photo to an iPhone and an iPod Classic, there will be two copies of that photo in the cache, totaling ~1.6 MB for that one pic, +even if the original pic is a 1 megapixel jpg that's only 150 KB in iPhoto.+

ICloud photo library size

Hi all,
I just have a quick question regarding iCloud photo library size.
What happens when the iCloud photo library is larger than the space on my iPhone?
My iCloud photo library size is 4gb (I am still within the free 5gb) however, the space on my phone is under 4gb.
All of my photos have been uploaded on the iCloud photo library beta for Mac/ Yosemite.
I'm aware that there are 2 options within the iCloud - Photos menu which are "Optimise iPhone Storage" or "Download and Keep originals"
Now I thought that regardless of which option you selected they would still store a local copy on your iPhone, but what happens when even the optimised versions take up more space than your phone can handle?
Sorry if I'm being a bit slow here, I'm just slightly puzzled by this one.
Thanks

One lesser-known feature of iCloud documents (I can't speak for Photos quite yet) is that storage on your iOS devices is dynamically managed - if a document hasn't been accessed from the iOS device in a long time, it will automatically be removed if space is needed (the way RAM is managed on a Mac) - all you have on the iOS device at that point is document metadata (title, etc.). If/when you need to access it again, it'll be re-downloaded. Note that it's different on a Mac - every iCloud document is cached on your Mac - I guess the assumption is that you have the space, and that accessing documents while working offline/off the grid is more important to someone who's using a laptop.
I expect iCloud Photo Library will work similarly, if not identically: On iOS a thumbnail of everything, larger images of items that are actually opened and viewed. If available storage starts to dwindle, the higher-res versions of the least-frequently viewed items will be removed until they're called for again. On Mac, a complete cache of everything, at full resolution.

Will deleting i-pod photo cache wipe pics off i-pod?

I've found the i-pod photo cache file that I want to delete (cos it has a ton of memory in the file).
My question is: can I do that and STILL keep all my pictures on my i-pod? Or is there some adjustment I can make, like manually keeping my pictures on i-pod?
Thanks

You can delete it, but if I remember correctly, iTunes will recreate it every time you sync the iPod with the computer.
iTunes uses that folder to store the pics in the size the iPod uses.
Pictures have to be on the computer for them to get on the iPod. There is no manual picture syncing.

IPod Photo Cache

In my Pictures folder there is another folder called iPhoto Library then another one called iPod Photo Cache. It's size is 71MB.
What is this folder and is there any point in deleting it? I know that since it's a cache it will come back eventually, but . . .
Thanks.

How to get rid of the iPod Photo Cache?

When exploring the iPhoto folder using Finder, there is a folder called "iPod Photo Cache"
I barely have any photo's stored on my iPod and yet the folder is 6GB! this is because i used to sync my entire library to my Ipod, but not anymore, yet the folder is still huge
i tried to remove it once, but that messed up my ipod and wouldnt let me sync any photos at all
how do it remove this folder or at least reduce its size without messing up my ipod?

andy
The only way to do it is to drag it out of there and into the trash.
Next time you sync it will take longer as the cache is re-created.
Standard Warning: Back Up First!
This file does get out of hand on some folks machines, and it removing it will not affect syncing.
Standard Warnng: Don't change anything in the iPhoto Library Folder via the Finder or any other application. iPhoto depends on the structure as well as the contents of this folder. Moving things, renaming things or otherwise making changes will prevent iPhoto from working and could even cause you to damage or lose your photos.
Removing the iPod cache is one of the exceptions.

I want to print photo's from my I3. They appear to be saved in photo cache but they wont open. Only way seems to be to e-mail to myself, any help?

I can't print photos taken from my phone. After syncing they appear in a photo cache but wont open and the software from my printer can't do it either. Also tried searching and having Iphone plugged in whilst printing and the printer also can not find the phone to download.

Photos taken with iphone are NOT part of the sync process at all. You should be importing them to your computer regularly as you would with any digital camera.

Dynamic Calc processor cannot lock more than [100] ESM blocks during the calculation, please increase CalcLockBlock setting and then retry(a small data cache setting could also cause this problem, please check the data cache size setting).

Hi,
Our Environment is Essbase 11.1.2.2 and working on Essbase EAS and Shared Services components.One of our user tried to run the Cal Script of one Application and faced this error.
Dynamic Calc processor cannot lock more than [100] ESM blocks during the calculation, please increase CalcLockBlock setting and then retry(a small data cache setting could also cause this problem, please check the data cache size setting).
I have done some Google and found that we need to add something in Essbase.cfg file like below.
1012704 Dynamic Calc processor cannot lock more than number ESM blocks during the calculation, please increase CalcLockBlock setting and then retry (a small data cache setting could also cause this problem, please check the data cache size setting).
Possible Problems
Analytic Services could not lock enough blocks to perform the calculation.
Possible Solutions
Increase the number of blocks that Analytic Services can allocate for a calculation:
Set the maximum number of blocks that Analytic Services can allocate to at least 500.
If you do not have an $ARBORPATH/bin/essbase.cfg file on the server computer, create one using a text editor.
In the essbase.cfg file on the server computer, set CALCLOCKBLOCKHIGH to 500.
Stop and restart Analytic Server.
Add the SET LOCKBLOCK HIGH command to the beginning of the calculation script.
Set the data cache large enough to hold all the blocks specified in the CALCLOCKBLOCKHIGH setting.
Determine the block size.
Set the data catche size.
Actually in our Server Config file(essbase.cfg) we dont have below data added.
CalcLockBlockHigh 2000
CalcLockBlockDefault 200
CalcLockBlocklow 50
So my doubt is if we edit the Essbase.cfg file and add the above settings and restart the services will it work? and if so why should we change the Server config file if the problem is with one application Cal Script. Please guide me how to proceed.
Regards,
Naveen

Your calculation needs to hold more blocks in memory than your current set up allows.
From the docs (quoting so I don't have to write it, not to be a smarta***:
CALCLOCKBLOCK specifies the number of blocks that can be fixed at each level of the SET LOCKBLOCK HIGH | DEFAULT | LOW calculation script command.
When a block is calculated, Essbase fixes (gets addressability to) the block along with the blocks containing its children. Essbase calculates the block and then releases it along with the blocks containing its children. By default, Essbase allows up to 100 blocks to be fixed concurrently when calculating a block. This is sufficient for most database calculations. However, you may want to set a number higher than 100 if you are consolidating very large numbers of children in a formula calculation. This ensures that Essbase can fix all the required blocks when calculating a data block and that performance will not be impaired.
Example
If the essbase.cfg file contains the following settings:
CALCLOCKBLOCKHIGH 500 CALCLOCKBLOCKDEFAULT 200 CALCLOCKBLOCKLOW 50
then you can use the following SET LOCKBLOCK setting commands in a calculation script:
SET LOCKBLOCK HIGH;
means that Essbase can fix up to 500 data blocks when calculating one block.
Support doc is saying to change your config file so those settings can be made available for any calc script to use.
On a side note, if this was working previously and now isn't then it is worth investigating if this is simply due to standard growth or a recent change that has made an unexpected significant impact.

In EJB3 entities, what is the equiv. of key-cache-size for PK generation?

We have an oracle sequence which we use to generate primary keys. This sequence is set to increment by 5.
e.g.:
create sequence pk_sequence increment by 5;
This is so weblogic doesn't need to query the sequence on every entity bean creation, it only needs to query the sequence every 5 times.
With CMP2 entity beans and automatic key generation, this was configured simply by having the following in weblogic-cmp-rdbms-jar.xml:
<automatic-key-generation>
<generator-type>Sequence</generator-type>
<generator-name>pk_sequence</generator-name>
<key-cache-size>5</key-cache-size>
</automatic-key-generation>
This works great, the IDs created are 10, 11, 12, 13, 14, 15, 16, etc and weblogic only needs to hit the sequence 1/5 times.
However, we have been trying to find the equivalent with the EJB3-style JPA entities:
We've tried
@SequenceGenerator(name = "SW_ENTITY_SEQUENCE", sequenceName = "native(Sequence=pk_sequence, Increment=5, Allocate=5)")
@SequenceGenerator(name = "SW_ENTITY_SEQUENCE", sequenceName = "pk_sequence", allocationSize = 5)
But with both configurations, the autogenerated IDs are 10, 15, 20, 25, 30, etc - weblogic seems to be getting a new value from the sequence every time.
Am i missing anything?
We are using weblogic 10.3

IPod photo cache file - how do I locate it?

Hi all,
On my iPod nano I keep getting the "some of your photos were not copied because they cannot be displayed on your iPod" message, but the photo albums I am syncing do not contain the photo mentioned in the warning.
I have had a look around and noticed that one member said there is an iPod photo cache file that does not get updated. So, I want to delete that and then resync my iPod, in the hope that this warning message will not re appear. The problem is I don't know where it is located.
For the record, I have also recently restored my iPod using iTunes 7.1.1 and this still occurs.
Thanks in advance,
Anthony.

well any suggestion would b appreciated, thanks!

TS1314 How do you change the default location address (in My Pictures) of the IPOD Photo Cache ?

How do you change the default location address (in my pictures) of the IPOD Photo Cache ?

You do no specifically. It sounds like you are syncing a folder to the iPod. In that case:
From a Folder on Mac OS X, Windows XP, Windows Vista, or Windows 7
The iPod Photo Cache will be located in the folder you selected to sync with.
Thus, you have to change the location of the folder you sync with.

How do I make a photo file size smaller? The photo is .jpg.

I need to make a photo file size smaller for some other uses.
imac Mac OS X (10.4.8) iphoto 5.0.4

Haha yes i forgot that you may not be using Apples Mail. Lets try the export then file>export, then under the heading "format" click JPG. Then click "scale images no larger then:" in the width field type "800" then the height field should change by itself. Thats what i do for emailing, it's usually the best trade between quality & size, that should be small enough to email. Best wishes JAG
P.S. when you first click "scale images no larger then" what's already in the width height fields? thats your actual photo resolution.
