[Web4lib] basic html question

[Richard James]

one of those answers that will occur instantly to someone on this list:
I recently edited one of my web pages to insert a graphical banner at the
head of the page. For some reason, the header would not display in IE if it
was a JPEG file, and would only display as a GIF. In Firefox et al, it
displayed fine in any format. The code used was <h2 style="margin-bottom:
0"> <img src="/icons/SummitIcon.GIF" height="69" width="700" /> </h2>

It's a trivial point, but the res of the JPG was much better and makes the
site look crisper. Any ideas?
