Thumbnail creation: no white background for GIFs

Watermark: disabled
Thumbnail quality: 100%

The thumbnails are now copied. Backround is white. But on the page the background is still grey. The reason is that the thumbnail path of the images is as follows:

I made som furter tests. Without the last it works. White background!

but this way the created is image is not gif ??

As I wrote, the thumbnails are now created in a correct way with white background. But flexicontent puts not just the thumbs in but changes them with phpthumb. Also, I guess q=95 means quality of 95%? If yes then this is wrong too because I set thumbs quality to 100%.

of course removing the f=gif will give you white background because you no-longer output a gif which has limited number of colors
