I have multiple volumes of a violin method book in InDesign CS2 and was considering upgrading to InDesign CS5. While using the trial version (which I just downloaded last night), every single of my eps files (hundreds of images across multiple documents) -- which were handled correctly by CS2 -- came up with the following error: "Error encountered while reading TIFF image. Image may be damaged or incompatible. Resave the image with different settings and try again."
Inconveniently, these errors were not collated into a single pop-up box when the document opened; instead, they appear one box at a time, as you page through the document -- so you have to manually close this error pop-up box hundreds of times.
Meanwhile, the problem is not with the image files themselves. Simply manually re-linking to the exact same image file corrected the image preview in each instance, for my Books 2 & 3. This would inevitably seem to suggest the image file was never actually damaged or incompatible.
However, in my Book 1, re-linking an image caused the program to crash each time I tried it.
The images themselves are EPS, not TIFF, and are listed in the links palette as such. I assume that it's simply the image preview which is a TIFF -- however, the pop-up box should be more illuminating for your users who don't do this for a living.
Meanwhile, the status of each buggy link is listed in the Links palette as "Okay." The inability to see the image correctly (and having to close a pop-up box each time you land on that page) is not, in my book, "okay."
I am planning to immediately un-install CS5 and return to CS2; I cannot possibly go through the laborious process of re-linking hundreds of links to image files that are perfectly fine. However, I wanted to post this feedback for the benefit of other users, or in hopes that the bug will be fixed. I love my InDesign and am very disappointed that CS5 is handling my documents so erratically.
Hopefully you haven't already saved the new file over the old version. Under no circumstances do you want to do that as there is no way to go back without having CS4 and CS3 to work through.
That said, if your CS2 file is still intact, try exporting it to interchange format (.inx), then open the .inx file in CS5 (or CS5.5 which is the current release, and not the same as CS5).
When you say CS5, did you mean CS5.5? It takes special effort to find a trial version of CS5.
In any case, please try running the Adobe Updater and updating to either 7.0.4 (if CS5) or 7.5.2.
Both fix a number of bugs.
