I have been working with InDesign for years and this is the first time I encouterred the following problem. Currently I am creating an online document with InDesign CS5.5.
The problem is that when I place (ctrl + D) an image (.jpg), some of them seem to "shrink" from their original size and become totally pixelated.
My original image is 192 x 380 px and it was placed as 46.08 x 91.2 px
I don't understand what might be the problem. For some of my images it seems to do this and for some not. There are some images that I have previously placed succesfully and then these same images are now shrinked when I place them. Could this be a setting change? I have tried everything, but nothing seems to work.
indesign don't pixelate images if you set them at 100% or less of the original sizes
1st: export to pdfx1a to see if the screen resolution is the problem.
2nd: select with white arrow and see if 100% is the numbre in the measures bar
pixelation should not be a prob if you have your jpg at 100%.
There are 2 problems pixelation and the image dimensions on the page. Placing at 100% solves pixelation but not necessarily the dimension problem—you need 72ppi actual res to solve both.
Thank you for your help on this. I opened the images in PS and indeed - some of the resolutions were 72dpi (placed fine), some 150dpi and some 300dpi (both resolutios placed smaller).
This means then that I have to change the resolution of all my images to 72dpi (a lot of work really for something that has worked earlier). What I don't understand is that why has this never been a problem before? I have done these kinds of documents with this same package over 200 pages and now this seems to be a problem. I have placed images with various resolutions with good results before. Is there a setting that I could tweak?

I don't see any difference in behaviour, just checked CS3 and it works the same.

Are you designing for web display? This would only matter if you are trying to view actual pixels at 100% where your ruler units need to be pixels.
As I mentioned in the previous post, this "resizing" has not happened before, even though I have placed images with higher resolutions than 72dpi.
The scale percentage that shows in the Transform panel is the scale relative to print output so if you change image resolution the image dimensions have to change.
ID does not resample when you scale—it's the same as resizing in Photoshop. If you change the resolution of an image with resample unchecked its dimensions have to change. So, a 5"x7" image at 72ppi becomes 1.2"x1.68" at 300ppi when you resize.
There is no print or image default. The output image resolution is relative to the scale of each image and shows as the Effective ppi in the Info panel when you select the image. The print resolution is chosen in the Print dialog and depends on the device
If your page dimensions are 800 x 600 pixels and you export the page as a JPEG, you would have to choose 72ppi if you want the exported JPEG pixel dimensions to also be 800 x 600.
In order to keep specific pixel dimensions without resampling the pixels on export to an image format, the incoming and outgoing res has to be 72ppi
