OK. I just did the same as you - tried again in my private public_html with
the upstream source and it worked fine.
Comparing the images with the ones in the test above showed that in each
file one 0x15 (^M), followed by an 0x12 (^J) had been removed from the file
(this occurred in each of gdtest.gif, gdtest.png and gdtest.jpg). So each of
those files was one byte short, and of course corrupt.
Replacing the copies in that dir means the problem is fixed, so you can
close this bug - nothing wrong with php4-gd.
Now I just have to find out why that byte sequence has been nobbled -
something is obviously not 8-bit clear round here.

Sorry for the slow feedback - debconf, holidays, catching up, etc.
