The transparent GIF image (a LaTeX formula), that I am going to attach to the
bug is not being displayed. It is there, but all white (not visible). IE displys
the image and I am also able to view it with image viewers (like Irfanview under
W2K or XV (linux). The Linux version of mozilla also shows this bug. 

Reproducible: Always

Steps to Reproduce:
1. load image 
2. fail to see image
3.

Actual Results:  
window remains white, no image to be seen.

Expected Results:  
display the black foreground of the image on a transparent white background

Attachment: a gif image with a transparent background

Comment 2

Neither acdsee nor the windows image viewer, nor paint is able to display this
image. The file looks like a PNM image with a GIF header, is this valid ?

Comment 3

[Emmanuel Bourg]

PNM support has been removed from the trunk (Bug 197530) so i guess this issue
will not be fixed unfortunately. A workaround is to generate PNG images instead.

Reopening.

Comment 5

[tor]

This is a valid GIF, just with a weird construction.  The problem is that the
image descriptor specifies an offset (285,253) from the logical screen of the
GIF, which is only 197x84.

Comment 6

Is it reasonable to try to display something outside the logical screen? 
I think mozilla does the right thing here.

Marked 'INVALID', as it works as it should, see comments 5 and 6.
