After installing QuickTime 5, I can no longer see JPEG images.
SOLUTION:
After installing QuickTime 5, you may notice that JPEG Images do
not display, or display improperly. QuickTime 5's default
installer puts an extension in your system folder called
QuickTime JPEG Update. This is meant for newer Macs running Mac
OS 9, and causes problems with older Mac OS versions.
To solve this problem, simply remove QuickTime JPEG Update from
your Extensions folder, inside your System Folder, and restart.
