I also have the same problem. I think it only happens when the image has been scaled with height and widht attribute. For example the preview image here:
http://www.eclipse.org/cdt/
will be partly or fully black.
If I drag the image with the mouse it will become visible.

I'm using Firefox 3, but the problem first appeared in one of the latest betas.
Running Linux Slackware 12.1.

I have this problem as well. It is most visible if you visit: 

http://www.xwiki.org/xwiki/bin/view/Main/Screenshots

All the images have been scaled to fit in the grid, and will display as black. If you choose "View Image" (right-click), the image will display correctly at its full-size

Additional details about the system I'm encountering this problem on:

Mozilla/5.0 (X11; U; FreeBSD amd64; en-GB; rv:1.9) Gecko/2008070114 Firefox/3.0

Using xorg-server, with the "nv" driver.

For both sites mentioned above, I have the same problem.

Mozilla/5.0 (X11; U; FreeBSD i386; en-US; rv:1.9) Gecko/2008070102 Firefox/3.0

I am on FreeBSD 7.0-RELEASE-p2/i386.

I do use the radeon xorg driver. Since I was told in freebsd-gnome, I checked XAANoOffscreenPixmaps (true and false) with no change.

I did a test with no plugins and no extensions with the same result.

I do not know what could be helpful. I could provide a list of all packages firefox3 depends on or all packages installed.

I'm seeing this as well. I'm also seeing bug #418826 (background images rendering as random junk), which I suspect may be related.

I built Firefox from source:
Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9) Gecko/2008062914 Minefield/3.0

It's built against Cairo 1.6.4, pixman 0.11.6, GTK+ 2.12.10; I'm using the X.Org server 1.4.0.90. (I also have Firefox 2 built against the same libraries, which works fine.)

I've tried out various different images to see which show the problems. The image format seems to make no difference, but the size does: the problem only shows up for relatively large original images. I think it's specifically for images bigger than about 64000 pixels; I've tried very wide and very tall images and this still holds.

However, I don't think this is actually a Firefox problem. I built Epiphany using the latest version of WebKit/GTK to compare against, and it has similar problems with exactly the same images. (No, I haven't accidentally built it with the Gecko backend -- I checked twice! "Mozilla/5.0 (X11; U; Linux i686; en-gb) AppleWebKit/525.1+ (KHTML, like Gecko, Safari/525.1+) epiphany") My guess is that it's a Cairo/pixman problem that both browsers happen to tickle in the same way...

My testcases and screenshots for both bugs are here:

I'd be interested to see whether this bug manifests the same way for other people that it does for me, and whether they're also seeing #418826.
If there's anything I can do to help track down the problem further, please let me know.

In contrast to what I said earlier, the problem does not appear with xorg.conf / device:

Option      "XAANoOffscreenPixmaps" "false"

I was able to reproduce the problem at a different computer with nv instead of radeon. The workaround did work, too.

This probably is it with some discussion and proposed workarounds: https://bugs.launchpad.net/ubuntu/+source/firefox-3.0/+bug/182038

Aha! So (after chasing links from there and Googling some more), this bug is actually a dupe of bug #411831, which has rather more useful discussion about the problem, and the root cause is an X.org server bug:

https://bugs.freedesktop.org/show_bug.cgi?id=15098

Turning on XAANoOffscreenPixmaps fixes the problem for me too, and looking at the latest version of xserver-xorg, it appears it's now off by default. So this one's fixed. :)
