[TYPO3-english] GIF image errors in error_log

[Frank Sonck]

Hi everybody,

While checking out my error_log file I saw that I have a continuous flow 
of similar errors:

identify: Missing an image file name
identify: Not a GIF image file (typo3temp/pics/xxxxxx.gif)

But there are no typo3temp/pics/xxxxxx.gif's on my page, only jpg / jpeg 
formatted images.

Checking my install shows everything ok. Does anyone have a clue why I 
have these errors?

Thanx,

Frank Sonck
