Cant view photos

I can upload photos but I cannot view them? It shows up blank. If click view original I can see it. What gives?

Check whether GD library/Imagemagick is installed in your server.

I am having the same issue and GD Library is installed. THIS IS DRIVING ME NUTS!

This problem happens with big sized photos, independently of its weight in Mega... GD resizing is working well with a 2Mo 800x600px picture, but will give up with a 200Ko 2400x2000px image...

Maybe some limit in PHP... I still don't solve this problem :-(

I have noticed in FTP that it stopped creating the _M and _T files for all uploads. It also doesn't like .JPG over .jpg. The uppercase also makes it fail.
