Well, it's a very simple PHP script that displays a random 1 of 2 images. It works fine on the GFL forum between the img tags, and every time you refresh the page you get a different image. Quite cool. The browser displays it as an image fine.
BTW as for Dreamweaver...
I don't use all the fancy buttons to do the code for me.
I use Dreamweaver ONLY for the Split-View which is quite handy. See, I can type HTMl code in one side of the screen like Notepad, and see what it looks like in real time on the other side of the screen. It's very handy.
And I occasionally use Dreamweaver to add in some popup Javascript menus because I don't know Javascript.
I've always used notepad before though.
