I want to resize all the thumbnails in my gallery. So I go into the Maintenance area and use the Rebuild Image Sizes to do the thumbnails 10 at a time.
I tried to do it to the entire gallery but it gets to a point and simply stops.
If I try to do it to individual forums, then the page just reloads without actually doing anything.
Appart from this, my gallery works perfectly. I am using GD2
