Quoting A-NO-NE Music madflute@anonemusic.com:
All the sudden, all the image nodes are spitting out this error wherever the image is used:
- warning: imagejpeg() [function.imagejpeg]: Unable to open 'sites/
default/files/images/<filename>.thumbnail.jpg' for writing in /includes/ image.inc on line 321.
- Unable to create scaled thumbnail image
The only way to remedy this, I found so far, is to reupload each images to the node. I started to doing it but there are hundreds of them, and I start to think there must be a better way...?
Sounds to me as if for some reason the permissions for Apache to write to the directory or overwrite the file has been modified. You might need to contact your hosting company if you don't have access to reset the permissions.
