Het leegmaken van de tijdelijke internet bestanden helpt soms. Maar dit is volgens mij niet de oorzaak van het probleem. Bepaalde jpg bestanden doen het niet goed zelfs al is je cache compleet leeg.
Een andere oplossing die je kan proberen is het volgende:
Verwijder alles uit de map "downloaded program files".
Dit schijnt voor sommige mensen te helpen.

Edit:
If you are the admin of an apache server and are having this problem, you need to turn on an apache environment variable.
This is because IE can't handle the "Vary" command in the header.
Add:
BrowserMatch "MSIE" force-no-vary
to your httpd.conf
Here are the people that did the research on it:

After you do that -- all fixed

I came across a couple of sites recently that systematically exhibit the problem discussed in this thread (IE "save picture as" will save JPG files only as BMP). I used a network sniffer to find out what was going on. Answer: the http headers sent by the server explicitly tell the browser not to cache.
It also helps to understand following: when you do a "save picture as", IE actually saves from cache. IE can save a jpg file as jpg only if the file exists in cache. If the file doesn't exist in cache (because cache was full or because the server told the browser not to cache), IE will only save as BMP, which is the format it uses internally. You can't really blame IE for what's happening here. It's only obeying the server's instructions to not cache the file. And if the file isn't cached, it's quite natural that IE won't save it as jpg. Would you trust IE to do its own jpg compression?
I have no idea how common "do not cache" headers are. There may well be several other reasons that prevent a file from being cached and therefore from being saved as jpg.
Devious thought: is there perhaps some secret setting that would tell IE to ignore the "do not cache" header??

header("Cache-control: private");
This was the solution for me. Now you force IE to cache the image and after that you can do a 'save as' and the annoying bmp-default is gone.
