Not currently, though it should be pretty easy to add that to the IF statement, CASE statement, and use the PHP imagecreatefromgif() function I would think.

I'm already add .gif extension,and works fine on my test boards.I'll hard test on my test forum 2-3 days then apply production forum.

Thanks

Thanks for your Plugin.

I want that a guest can view the thumbnails but not the full full size oft it.
But it does not work.

My stettings:
Guests to View Thumbnails yes
Unregistered / Not Logged In usergroup set to NOT have access to download attachments

Did you follow all the steps? The attachment_watermark.php file is still required for the Guest Thumbnail feature also. Though, you can just leave the watermark fields empty if you don't want to use that part.

yes I did
here is my attachment_watermark.php
