Temp internet cache / pictures only save as .bmp - "untitled"

Hey, I have a few questions about the temp files cache. Here is my problem:

I save a lot of pictures onto my HD. I had this problem with XP as well, but am having it again with Win7 Pro 64. After a little while, IE will only allow me to save the files as .bmp and they lose the filename--which is replaced as "untitled".

I know this has to do with the temporary internet cache size.
What do you guys keep your cache size at (the default is 50mb)?

The recommended fix is just to delete temporary internet files, but when I do this, I lose cookies and stuff and have to re-enter forum passwords.

Even if I go into IE tools and delete history---if I deselect cookies and keep the box checked for "keep cookies on favorite websites" I sometimes have to reenter passwords and usernames into forums. Also--even though I have temporary internet files deleted...they do not delete when I close IE....does this feature only pertain to the actual browsing history?

I googled the problem and one suggested solution for XP was to deselect the "do not save encrypted pages to disk" box. Is this safe? How can I fix this problem so I can save picture files as their original file type like .gif .jpg or whatever?

Ok,

I have 5.59gb in the temporary files folder...ok to get rid of this?

Temporary internet files are just about empty @ 3.16mb

Ok, cleared everything...We'll see how this works out.

Thanks

Holy crap. Yes. You should be deleting temporary internet files on the regular. They are really of little use.

He's talking "temp"....not temporary internet. But both should be cleaned out regularly.
