I'm using version 2.0.2
The insert page works fine. It's the update page that's cause problems. When I want to replace an image with a new one name newimage.jpg, the main image and the thumbnail should be newimage.jpg and thumb_newimage.jpg. In my case it's newimage.jpg for the main image and newimage_1.jpg for the thumbnail.
I'm attaching my update page.
Thanks again.
Regards
Rune
