or
When using the GD image library allowed image types are only JPEG and PNG.

I split this from an unrelated thread.
Is this a new problem, or has any changes been made to your server.
QuoteWhen using the GD image library allowed image types are only JPEG and PNG.
Unfortunatly GD ONLY supprts JPEG / PNG / WBMP images. TIFF / GIF / BMP /etc are not supported.
If it really is a JPEG you could be runing into a problem with the format of JPEG (CMYK vs RGB), if that is the case then upgrading to GD 2.0.22 might help.
