IPhoto - how to create jpegs on a CD at 72 dpi?

I need to provide a copy of a picture on a CD. The image needs to be a JPEG at 72 dpi. How do I do this? The original file is in iPhoto and is 2448 x 3264 (2.2MB).

Correct as stated
DPI is Dots Per Inch - so without inches you have no DPI - digital photos have only dots (pixels), no inches
Give inches (for example what size is the image going to be views at) figuring the required Dots (Pixels) to result in the image be de isplayed at 72 DPI is a very simple math problem - for example if an image is to be displayed at 10" x 10" then it must be 720 pixels x 720 (720 dots / 10" = 72 DPI)

How to create jpegs from pdfs without pixellated results

I have been creating jpegs from high quality pdfs (typically 20-30 MB files) of maps (paper dimensions roughly 2 ft by 3 ft) with no problems until this week. I use the export function in Adobe X Standard and select jpeg. Did I recently get an update which changed my settings? Now I notice that sometimes the process generates a progress bar which says it is optimizing the content for the web. I don't remember seeing this either. Previous conversions worked great and the jpegs could be blown up on the screen with crisp detail. Yesterday I did the same process with a new map (I checked it for good resolution and the pdf can be zoomed way in with no loss of resolution). But the resulting jpeg pixellates very quickly when zooming in. What gives? It may be possible that this new map (pdf) is in layers. I think the others were scans of the paper maps. Does this affect the conversion? Also noticed that the jpegs now have little lock symbols on them. Is that related? I don't think it is, because a map I recently converted has the lock symbol on it and is OK (as a jpeg). I am converting the pdfs into jpegs so I can import them into Autocad.

As the helpcenter(2005 helpcenter) has missed this bit of documentation (on UserQueries) could someone please provide an example of using this object
thanks

How to save JPEG from PS5 with a different DPI?

I have a scanned image with DPI 4800.
I have prepared the image for the printing in LAB, so I have tried to change image DPI to 300.
In PSD file it works, the DPI was changed, but if I try to save the PSD as a JPEG file, the DPI in JPEG is not changed, or more precisely it is not set.
Thank you for explanation.

Why LAB? ...or do you mean "lab"?
How did you try to change the ppi?
If you have a PSD at 300ppi and Save As... a JPEG it should keep the 300 ppi. Don't use Save for Web.

How to create a new place in iPhoto 11 without doing any harm?

Yes, I know how to create a new place for a photo -- theoretically:
Select the photo.
Make sure the Info icon in the lower right portion of the iPhoto window is clicked and the too-tiny-for-any-but-the-youngest-eyes map is displaying.
Click in "Assign a Place..." and begin typing a place that iPhoto will search for. It searches in both "your places" (i.e., those that you have already defined) as well as in Google Maps.
When you see a place in the search results list that you think might be close to the one you mean, select it.
A pin appears on the itsy-bitsy map. Move it to the exact place you mean. You can make controls appear on the map by moving the mouse over the bottom of the map. The controls allow you to zoom in and out, and to change views (Terrain, Satellite, Hybrid). When the pin is where you want it, click it. The current name of the location appears. Modify it to the name you want, then click the check mark.
That's "all" there is to it ... except for a couple of "gotchas."
There's a difference between what happens when you select a place that you've defined and when you select a place that Google found in the search results. If it's a place that you've defined, and you then move the pin to a new location and/or change its name, this will affect all photos assigned to the custom place. In effect, you are modifying the place.
All places have a radius associated with them, thereby making them circles. You can adjust the radius only in the Maintain My Places window. In the itsy-bitsy map it doesn't even appear. However, if the newly defined place overlaps existing ones, all the photos assigned to the overlapped places will be assigned to the new one. Their pins will remain where they were.
Now, before anybody suggests sending feedback to Apple, let me emphasize that I have been sending Apple feedback on the wrong-headed implementation of Places since iPhoto 9.0. New versions have come and gone (the current one is 9.1.2), but these "features" have remained. So my purpose in opening this thread is to consolidate work arounds to these "features" in one place. My work around:
Whenever I define a new place, I select only a single photo. I try to name my places so that I can distinguish them from those that Google finds. In order to avoid Gotcha 1 I select a place that Google finds and try to place the pin close enough to where I want it, but far enough from any other places that I've defined. I give it a name that I can easily find it Manage My Place.
I immediately open Manage My Places and select the new place. I first note the pins near it, then decrease its radius, move the pin to the desired location, note the nearby places, and give it its final name.
I then view Places and navigate to the new place to view the photos assigned to it. If I'm lucky, there's only one. Otherwise, I have to reassign the other photos to their correct places.

So... in the hope it will not confuse folks more, let me be more specific of a procedure that works for me...
Procedure to create a new My Places location.
OK there is more you can do with a non-GPS Coord linked photo.
Click Info and then click Assign a Place in the lower right of screen. (if your photo has a location linked to it already the Assign a Place will NOT show up.)
Choose a location name near the actual location that Google Maps can find.
Click that location in the Google Maps list that appears and your photo will be temporarily assigned to that location.
Now type over that location name in order to make sure to give that location a unique name that will show up in your My Places list and click that name after you have typed it to be sure it is accepted.
Now in iPhoto click Window/Manage My Places and go the that newly named location in the large My Places map. There's no easy search. You have to run down through the alphabetical list.
Drag the flag to the location you want this place to be and click Done.
The location name is now in your My Places list at the location you dragged the flag to!
It is important to note that only your unique named locations show up in your Places list, so if you want to modify the location coordinates you have to establish a unique name for it.
This is much more complicated that previous iPhoto versions!
But Yeah!!!!!!!!!!
It really works!!!!!!!

How to create a browser to view JPEG files?

How to create 2 or 3 links URL in a jpeg ?

How to create 2 or 3 links URL in a jpeg ?
Do i use photoshop ?
Thank you

Images cannot contain links. All that stuff is done in the web page source code, e.g. using image maps, interactive SVGs or JavaScripts that track coordinates and respond accordingly. You will have to use a web authoring tool like Muse or Dreamweaver to produce such stuff, but since you seem to be a complete beginner, I strongly urge you to read up at least on some basic stuff about HTML, CSS and how the web ticks in general or you'll be forever lost.

In iPhoto, how do I create a new library?

I can't seem to figure out how to create a new library within iPhoto ...

Hold down the option (or alt) key key and launch iPhoto. From the resulting menu select 'Create Library'

How to create a letterpress card using iPhoto on my iMac?

How to create a letterpress card using iPhoto on my iMac

You CAN'T do it with Flash Player. You'd need Flash Professional and you'll need to learn Actionscript. I've been through the Lynda.com training for Flash, and it's not something you learn in a few minutes or even hours, or can be gleened from a guide. It takes days and possibly weeks, even if you're already good with Photoshop and/or Illustrator and Fireworks.

I have on iPad iPhoto, how do i import to my mac the albums that i created on the iPad iPhoto?

I have on iPad iPhoto, how do i import to my mac the albums that i created on the iPad iPhoto?

Here's a Mac World article that may help. Still not perfect but will help transfer edited photos. If done in groups you can re-create the Albums on the Mac.
http://www.macworld.com/article/2010727/the-ultimate-iphoto-workflow.html
Basically the process requires "Sharing to iTunes" through the iPad's app then syncing with iTunes. The shared photos will be found in the File Sharing section of the Apps tab of it's sync settings, not the Photos syncing tab.
The other method is to save your edited photos to Camera Roll and import through iPhoto on the Mac or Photo Stream. Once again you'll need to do it in groups to save your Albums then recreate them on the Mac.
I should also mention I have yet to use iPhoto on the iPad and there could very well be a better method out there. I have been researching for the best work flow to copy photos from my iPad which will be copied to the iPad with the camera connection kit, organized and edited on the iPad then copied in that state to my Mac once I get home. I like the idea behind Photo Journals while traveling and was disappointed to find they can not be saved, backed up or viewed through iPhoto on the Mac. I'm sure there are easier work flows but this is probably close to the route I will be taking.
Any other input?

How to create album (or folder) within others in iPhoto?

I am a recent convert from Windows. I used MS Digital Image to manage my photos. I could create a folder, add sub-folders underneath, and even sub-sub-folders if I wanted to. And I did. E.g., I could name a folder "vacation 2009" and create sub-folders under it for each place visited.
I can't seem to do this in iPhoto. When I migrated my photos over to iPhoto it totally trashed the existing folder heirarchy. It is a mess now! I'm trying to rebuild the tree, but iPhoto is not cooperating. I can create a folder or an album but it won't let me create a SUB folder or album. It just drops it under the same tree. I guess it thinks it is smarter than I am or else it's one really lame bit of software.
I even thought I would try to create a folder/sub-folder heirarchy in Finder, but Finder can't even "find" my photos! I'm REALLY ticked.
Anyone got a handle on this?

a couple of things
You are thinking of a file management system - that is not what iPhoto is
iPhoto is a database and if you tag your photos you can find them instantly using the search window in the lower left or with smart albums
For the organization you want you use folders (folders hold folders or albums) and albums (albums hold photos) - events are best left as just buckets of date organized photos
You do not use the finder - doing so can damage the iPhoto database - use the many build in photos access procedures in the OS - <a href="http://web.me.com/larryhn/iPhoto_08_(version_7.x.x)_FAQ/Accessing_iPhoto_Photos. html"> click here for a discussion on the many correct and safe ways to access your iPhoto library photos.</a>
different people use different strategies but I go with the old j-school 5 Ws - Who, What, When, Where and Why - I use faces for who - when is automatic form my camera and since I have a GPS camera where is automatic too - and I use key words for what and why - so I can instantly find any photo - want a photos of my wife, daughter and dog in New York in 2006 - or all photos with elephants in them - instant - try that with a file based system
You need to learn iPhoto and change your thinking from managing files to managing photos - the old tutorials help (although some commands have changed location) - and it would be a worthwhile investment of time to take the iphoto tutorials - http://www.apple.com/findouthow/photos/ - they are very helpful and will save you a lot of time and frustration. -- and there are videos under the iPhoto help menu ==> iPhoto help ==> videos
And you may want to start over with your old folder structure as a starting place - to do so just quit iPhoto and drag the iPhoto library to the desktop and launch iPhoto creating a new library - make sure the iPhoto preference to split items imported form the finder into events is not checked and then drag folders to iPhoto - it will create events matching the folders

IPhoto '11 and RAW/JPEG handling (good/bad) ?

I've upgraded to iPhoto '11 and discovered (don't know if it's a new feature) that iPhoto handles RAW extremely well. I can view RAW files and edit etc in a smooth manner - which is great.
Actually it's so great that i've started shooting photos in RAW only (so i don't get duplicates in iPhoto when importing RAW/JPEG) - but is it a good idea to shoot/import RAW in iPhoto only? (and skip the JPEG file).
If it's better to shoot/import both RAW and JPEG, how do you guys handle the identical pictures (RAW/JPEG) in iPhoto?
Finally, if i only have RAW in iPhoto, how do i 'export' the RAW picture? If i drag and drop the picture to desktop, RAW is automatically converted to JPEG (which is great in 99% of the times).
Hope to hear some of you guys ideas regarding this subject.

When you import a Raw to iPhoto it automatically creates a jepg preview of the file. Why? Because you cannot do anything with a Raw: you cannot print it, use it a slideshow and so on. However, with this preview you can work with the photo immediately.
Shooting in Raw+Jpeg is a bit pointless as you have this automatic preview anyway.
if i only have RAW in iPhoto, how do i 'export' the RAW picture?
File -> Export and set the Kind to Original
Dragging to the Desktop accesses only the latest version of the photo.
