[Typo3] Abusive JPEG conversion

[Francois Suter]

Hi all,

I have one of my Typo3 sites doing something weird. Some (but not all) 
JPEG images are converted to GIFs when displayed in the pages. Those 
GIFs have a gray-level palette and look accordingly ugly. In the 
backend all thumbnails are fine though.

I checked the Install tool and all parameters seem correct. In 
particular, [GFX][thumbnails_png] is not set so - as far as I 
understand - JPEGs shouldn't be forced to GIFs (and anyway this should 
affect only thumbnails).

ImageMagick version is 6.0.6. Could this be creating problems?

Has anyone observed a similar behaviour?

Thanks for any hint.
