what type of file should i save a picter such as my profile image as, cause its a bit fuzzy (its a JPEG) Answered

jpg is okay for size - but if you save it with mspaint, it will save VERY compressed and fuzzy. Save as png as Zero suggests - its practically lossless, and has good file sizes for small images.

Yes, I use .PNG all them time because it is good quality but still good file size.

(PNG= Portable Networks Graphic, I think = D )

I would use a .png first.

Small profile icons usually do well as a .gif or .png, depending on what the site will accept.
If you're using software like Photoshop, Gimp or paint.NET, it's as simple as 'File>Save As', and choosing a different file type. The second two are freeware, I recommend looking into them if you're still using bundled software.

The 'fuzz' is caused by compression, you can read more about it here on wikipedia
