I have two versions of the image 'balloon.png'.
The .PNG looks better but it does not work properly on MSIE because it has an alpha-transparency.
So I want to serve the UGLY .GIF to MSIE users but the .PNG to everyone else.
Right now I use this to display the PNG version:
document.writeln("<img src='balloon.png' onmouseover='fix(\""+j+"\");'>");
I need something like this, but my syntax is off...
if (browser==MSIE) imgExt=".gif" else imgExt=".png"
document.writeln("<img src='balloon."+imgExt+"' onmouseover='fix(\""+j+"\");'>");
Any ideas how?
