Thread:Project:Support desk/Image upload problem in a new installed Mediawiki 1.21.1/reply (8)

I encounter the same problem as yours. And according this link - [ RESOLVED ] Error creating thumbnail: Unable to save thumbnail to destination I solve this problem. I hope this could help others.

Adding the follow code to LocalSettings.php :

$wgTmpDirectory = "$IP/images/temp";

Update:


 * 1) You should also create a new directory named 'thumb' in the ./images folder:.
 * 2) And then check the other files(directories)'s privilege in the folder 'images':.
 * 3) Finally, change the privilege of 'thumb' to the same as others:

What's more, I prefer to using 755 rather than 777 for the 'images'. Good luck!
