From your screenshot, only the uppercase JPG files are causing the problem.  I've never seen this happen before.  Did you change the allowed image types in config from ALL to something else?  If you rename an image from IMGxxxx.JPG to IMGxxxx.jpg, does it work then?

[Bulldog]

no i did not change that in the config page
if i change to lowwer case it still don't work

Perhaps your images are corrupted somehow.  Can you verify the problem images are not corrupted?  If you can, attach one to your next reply so we can take a look at it.
