upload image broken

Hello,

I’m using 2.0.61 version of the plugin.
When I try to upload an image to an existaing album I have the following error message : Upload complete / 0 images were uploaded.
and quickly on the alert icon alt tag : “HTTP Error”.

I tryed to re-install the plugin manually but it was unefficient.

I have few error in the log file, may be it will help you to understand my problem.

Thanks for your help;

Thomas
