So have it actually converted it to jpg? It's difficult to test with a png file which is just larger than the allowed file size yet smaller than the server allowance after conversion.. so I never know whether it's really working.
A problem I just found. But first, the addon is still working great for me!
BUT, I just made some changes to the forum png logo, and uploaded it. And the transparent background didn't work!
It took me a whole hour before I realized this addon apparently converts admin panel uploads to jpg!
Is it possible to make the addon ONLY convert forum message uploads? That way we don't have to disable it to do admin management functions...?
