Fails on every picture with an error message => solved

Could you give us a hint on how you resolved this?

Oops, sorry I haven’t been clear.

The actual problem was a write permission problem on the files and directories. I did something like this (you need shell access):

find ./uploads -type f | xargs chmod 666
find ./uploads -type d | xargs chmod 777

This basically means, get all files in the uploads folder and change permission to 666, and get all directories and change their permission to 777.

If you don’t have shell access, you can do the same with an FTP¨client, it just takes more time.

As you see, the “error message” is very unhelpful, and could be better.

Thanks, although isn’t it a bad idea to have the folders set to 777 within the uploads dir?

edit: Unfortunately applying the settings you suggest doesn’t seem to fix the problem

777 for folders: if Apache does not operate under the same user as FTP, you might not have a choice.

I can’t remember having problems with this plugin previously. I imagine a recent change in WordPress broke it in some way ??
