I've tried opening one and saving it, but am having no luck.
Where would I find the pixel ratio, is it in file properties from a right
click ?

Thanks for helping

Hi Peter,
the pixel aspect ratio is the terminology used by Adobe in Photoshop CS2.

The actual way I found easiest to correct the error was to use IrfanView the freeware image viewer

if you load one of the corrupt files and press "I" to show file information you should see an entry called resolution, (a different terminology for the same thing - pixel aspect ratio) - with a normal file the two values here will be the same.

in the corrupt files I found that these were wildly different, change them to something like 100 x 100 (check your OK images for the correct figure )

as an experiment I manually corrupted a file to have a 1000:1 ratio and the result is shown in the attached image

obviously with the 11000:1 error you will not see anything but a vertical line for the image thumbnail but the 1000:1 shows a representation of the problem

Hope this helps explain my thinking - Also as IrfanView has batch edit facilities it may prove a useful tool when large numbers of images are involved

Yes, that looks like it except more so.
I'll give it a try and get back to you.
Thanks for helping :-)

Irfanview is by far the best viewer to be using, both for its ability to
deal properly with files that have this sort of invalid data, and for seeing
what that data is.

I had same problem with some of the images in 1 sub-folder when copying
photos from laptop with XP to desktop with Vista. I checked and found they
were all photos which had been rotated from landscape to portrait on laptop.
I rotated them back to landscape in original XP programme and copied them
successfully - they are now visible in Photo Gallery (hope it stays that
way!) where I then rotated to portrait.
