|aaaakumar, I;'m sorta with Paulsep here, confused. Try RIGHTCLICKING on the image you can't open to get a drop down menu.|
From that menu, you can select the proggie to use when opening. IE opens most (but, not all) things. Try it first. If it opens the image, do it again. This time check the 'always use' box and it should automatically open future images of the same type.
If it still won't open, give Irfanview (free @ http://www.irfanview.com) a try.
That's what I use and I've found it'll open some things IE won't and it's an excellent graphic editor (far better than Paint IMHO).
