Default Image Rendition or resize image automatically

We use the column Rollup Image and have the blob cache enabled to use image rendition.
Is it possible to use this publishing image column with a default rendition (not full size) so the user has not to choose the rendition (or cannot choose it)?
Or what would be the best practise to get automatically resized Images? By publishing Image column or better by JavaScript?

Hi,
According to your description, my understanding is that you want to you want to know about how to use PublishingRollupImage Column to display a default image rendition and how to get automatically resized images.
Firstly, I suggest you can use the automatically resized in the rollup publishing image column. As the image renditions will choose for different device such as mobile phone, if they display as a default rendition, then it can't be enlarge if user want to
see more clearly.
About how to get automatically resized images, you can get image with RenditionID using Jquery.
Here is a code snippert for your reference:
<script type="text/javascript" src="http://ajax.microsoft.com/ajax/jquery/jquery-1.7.1.min.js" />
<script type="text/javascript">
$(document).ready(function() {
$image = $(".article-content").find("img");
$image.each(function (i) {
var imagesrc = $(this).attr("src") + "?RenditionID=5";
$(this).attr("src",imagesrc);
</script>

Problems Using Image Processor to Resize Images

Hello,
I'm perplexed on this one.
In the past, I've used scripts in Photoshop to downsize my large Camera RAW images to an appropriate 1920 x 1080 size for subsequent export to Premiere Pro.
Worked like a charm numerous times.
Now, when I try to do the exact same thing and check the destination folder AFTER running the Image Processor routine but BEFORE bringing them into Premiere Pro, they are all 1620 x 1080 instead of 1920 x 1080.
This doesn't work.
I keep checking around for a little typo in the various stages but cannot find one. Any thoughts?
I recently had to reinstall Photoshop and changed one of the settings in Preferences to 32 bit instead of 16 bit. I don't think that has anything to do with this, but I wanted to mention it just in case.
Here is a screen shot:
Thanks!

(PS: I know that's a screen shot from a Mac, but I believe this issue is platform independent)

Thanks so much for your help gentlemen!
Sorry for the delay in responding. The deadline for submitting my film is fast approaching and I've had so many different things to do, all of them important.
Surely these are useful pointers you are giving me. Cropping has been unsuccessful, as has been using the Image Processor. Russell Brown was scratching his head about the failure of the Image Processor to work on this and has told me he will work on it after Photoshop World finishes.
Incidentally, thanks for the video of his on Content Aware Scaling!
I was unaware of the Alpha Channel aspect which REALLY makes it an amazing feature. Alpha Channels are slightly beyond my skill level, but not terrifying. For some reason paths and alpha channels have been a little harder for me to learn in Photoshop; I've picked up many other things rather quickly.
JM, I've tried floating a layer by duplicating it. I called that layer "THIS IS BETTER" (below). Then I tried to adjust the image canvas size as shown by the screen shot below. Is this what you were describing? I tried to change that canvas size to 1020 x 1080.
I then got a warning message about my image being clipped:
And that apparently resulted in this "clipped" image below:
Any thoughts on that particular avenue of inquiry?
Thanks for your help.

I have both Photoshop 4 and Photoshop 6 on my computer. When I am in Bridge and want to open an image by double clicking, it automatically opens in 6. I see, when I go to "open with" 6 is listed as "default" How can I change the default to open an image with a double click in 4?

You can associate files from the Bridge level and the Desktop level.
In Bridge CS4, go to Preferences > File Type Associations and change it to Photoshop CS4 for the file types you want.
If you want to open files from the Windows Desktop in CS4, these are the instructions:
Do this from the Windows Desktop:
If you want your image file to open in Photoshop and it doesn't, right click on it and choose
Open with > Choose default program… select Photoshop CS4 or CS6 and checkmark "always use the selected program to open this type of file".

Mail is automatically resizing images

When attaching an image to mail it is automatically being resized to approx. 160 kb no matter what size the image really is. I can't seem to find any preferences in Mail that apply and Aperture export is set at Original size JPEG. Any clues? Recently upgraded to Leopard and iLife 08'.

Steve:
Are the photos also being resized automatically in dimension? You should be getting an window with the option for picking the size of the image to send, small, medium, large and actual size. Are you getting that window when you select the photo and click on the email button? Also at the bottom of the email window will be a menu button on the lower right with the size options once the photo is in the email.
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've created an Automator workflow application (requires Tiger), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. It's compatible with iPhoto 08 libraries and Leopard. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.

Site that automatically resizes images based on browser size

Hi. I need to make a site that automatically adjusts the size of the images based on the browser size, but keeps the image quality. Does anyone know how to do this without using flash?
I basically want the site to perform like [http://www.shotview.com/|http://www.shotview.com/] . Thanks for your help.

first time accessing website get screen size info using javascript and then redirect to next page and store screen size info into session. then, when requesting pictures from browser use custom servlet, mapped to image extension, that renders images to different resolution.

Does Photoshop CS6 autosharpen resized images?

Hi all,
I've been using Photoshop for my Photography for quite a long time and I have recently upgraded to Photoshop CS6. Whenever I resize my images in CS6, I get the feel (from looking at the images) that the application has autosharpened my images! I am quite sure about that effect because my resizing principles have remained the same since using CS5. And in CS5, whenever I resized to that same size I am resizing in CS6, I used to run the Unsharp Mask Filter to get my images look at their best! So there must be something going under the hood in CS6, or am I missing something obvious? Basically, I want to be in total control as to how much sharpness I want to apply to my resized images!!
regards,
Ali

In fact Adobe added the new interpolation method Bicubic Automatic new in CS6 and Adobe change Adobe's default Photoshop's Interpolation preference setting to the new method. However Adobe did not do a good job adding the new feature. If you leave Photoshop Preference set to Bicubic Automatic you may run into problems if you use scripts that transform things. For if the script tries to retrieve, change and restore your Photoshop Interpolation method Photoshop will wind up with an internal error. There are many bugs in CS6 this is one Adobe has not address yet.
Bicubic Sharper may work well on large un-sharpened soft images. It does not work well on images that have been sharpened.
Adobe scripts like the Fit Image Plug-in always uses Bicubic interpolation. Layer Transforms prior to CS6 always used Photoshop Preference Interpolation method. That is why the script I write retrieve this setting change it to Bicubic , transform then restore the Preference. CS6 now let the user set the interpolation method for some forms of layer transforms not all.

Add image renditions to an existing picture library

Hi all,
Consider the following scenario, i've created a new site using the Blog template. Which created a default picture library named "Photos". We have been experimenting with SharePoint and mobile devices so I thought i would give Image Renditions a
try.
What I did, is enable the Publishing features on the site and saw that the Image Renditions appeared on the Site Settings screen. What it also did, was create a new library named "Images" which has all the image rendition capabilities enabled.
Yet, to my disappointment, the "Photos" library which was created earlier and is now stuffed with data, doesn't have those capabilities :(
So now my simple question, what steps do I need to take in order to use those Image Rendition capabilities on the "old" library? I've already tried:
- Enabeling the Photos library to a Site Assets library
- Add the content type "Image" instead of Picture.
Thanks!

Downsampling algorithm for JPG images in both PDF or automatic mode

Hello,
the question is: which algorithm is used when images are formatted by the Folio Builder in the Folio or Articles properties?
My question is focused on the static images and I know that it would be better to resize images before placing them in the document.
The question is also related to the image format.
If I use a non-compressed format such as the TIFF (without compression) then the images are re-formatted as JPG or PNG.
We know that both automatic and PDF option saves images as JPG or PNG depending by the transparency contained in the graphics.
After this considerations I think that save static images as PNG before placing them in InDesign document could be a solution to obtain images without any compression.
Am I right?

Thanks Ankit,
but in the article there is no response to my question: which algorithm is used to downsample the images and wich is the best way to mantein the images quality in both Automatic and PDF.
This is the problem.
Thanks

Resizing images

I am using Photoshop CS (older version).
I am having a problem with resizing images. Prior to sending this, everything was working okay and now nothing will resize. my file path was file menu > automate > batch > and then I would choose my source and destination for the resized images. In the end, all the newly resized images would stay the same size as before. Can someone please help me with this???

Neil,
Have you selected the "resizing" action in the Batch dialog?

How to resize Image Jpeg ?

Moving an image; where are resize handles?

I'm moving (move tool) some significantly larger images into a smaller image. I remember watching a video some where that said if you hold down the ___ key, that you'll automatically get the resize handles. Anyone know what that key is?
Also, is there a way to move the image in to the smaller image, and not have it be so huge, without having to change the resolution size before moving it? (Ideally I'd like to move the image in at about 1/20th the original size, making it fit into the 2nd image)
Thanks!

Hello!
Hitting the V key will show you the transform controls, IF the relevant option is selected for the move tool in the option bar AND if View>View Extras (Command+H) is activated.
Command+T will show you the transform handles, no matter what option is set for the move tool.
I need more info for your second question: what are you trying to do? Do you do that on a routine basis?
If yes, you could set up an action that moves the image to an other document (all depends how many images are open at a given time), then scales the newly pasted layer to 5% its original size.

Safari resizing images, again...

Some years back, around 2007, I started a thread about Safari automatically resizing images that are larger than the window. That "feature" magically appeared with one Safari update, and quickly disappeared with another update. Well, it's now July 2011 and a new Safari update Version 5.1 (6534.50) has brought this annoying feature back.
I'm sure there is no way to disable it. I have looked through the preferences, developer and debug options. Why can't Apple make up their minds or at least give us the option to turn this thing on or off!!!!
Check to see if Safari is resizing with this image: http://img51.imageshack.us/img51/9117/g9img0272sj.jpg
If it fits within the window and your cursor shows a zoom icon with a plus Safari is resizing. Those of you with high resolution screens may not experience resizing as most images will fit within your window.
You can also tell if Safari is resizing images by grabbing the bottom right window resize handle and resizing Safari. You'll notice the image will change size to fit within the window. See this pic for an example: http://img585.imageshack.us/img585/3074/screenshot20110722.jpg

This is under 10.6.8 Snow Leopard, not 10.7 Lion, although I would expect the same behavior with both.

Firefox will auto resize images, but not text files.
Safari will auto resize text files, but not images.
I'd love to turn auto resize for images on and off in Safari.
Does anyone know how to do this, with a style sheet perhaps?

Problem trying to batch resize images from bridge.

I am trying to batch resize images from bridge. I am on windows 7 desktop and using CC, I select the images in bridge, tool bar>tools>photoshop>image processor. After doing this, photoshop CC opens but no images open.

open photoshop, open actions pallette, click new action (windows > actions (or Alt+f9)), click record, open your image, resize it, click stop action.
then use file> automate > batch
the action you just recorded will be ready to use, select the folder with all your photos (wise to work on a duplicated folder incase you mess up)
run the action. wait while photoshop opens and resizes the images one by one.
check in folder if the images resized how you expected.

Setting for whether to resize images or not in exportContext.propertyTable?

I have a plugin that creates multiple renditions of various sizes. For the sizes I require, the image sizes are set with the two properties LR_size_resizeType and LR_size_maxHeight.
The issue I am facing is that the rendering process only reduces the sizes if the "Resize to Fit" checkbox is checked in Export settings. If left unchecked, all renditions are set at the same size of the original image. I've attempted to find out which property this checkbox may effect, but don't see any difference in the keys/values of exportContext.propertyTable between having the checkbox set or not set.
I hope somebody can help advise on the following:
* Is there a property I can set to force LR to resize renditions, whether in exportContext.propertyTable or elsewhere?
* If not, is there a property in my plugin's preset values that can set this checkbox to 'on' when the plugin is installed?
* Any other approaches to force LR to resize renderings without having the user check the 'Resize to Fit' checkbox?
Thanks in advance for any help.

Thanks for the advice Rob. The magic setting seems to be LR_size_doConstrain. When set to true, the images are now resizing correctly, whether Resize to Fit is checked or not.
