I've recommended to a number of my friends and coworkers that they get firefox for a nicer time browsing this here interweb.
If you are still using Internet Explorer, it's important that you get it updated rightnow. There is a current vulnerability in IE that means simply looking at a .jpg can let bad guys do nasty stuff to you. Since the web seems to have a whole lotta images on it, it means that it's impractical to browse with images turned off. So go get that fixed.
Firefox coincidentally has a similar issue for .bmp images in an older version. The current version is all good, but if you don't have it, best go get it now. I looked into all the technical hoo ha and it comes down to a single library with an error in it.
Called libpr0n. What's up with the name?
From their FAQ:
- Why the name "libpr0n"?
- The main goal of the library is to render pornographic images in an efficient way.
