This might sound dumb at first but I've been trying to figure this out all day. Well for 3 hours.

You know how in regular HTML you can type:
/images/spacer.gif

and it will be the same as:
http://yoursite.com/images/spacer.gif

Well, when I do that in PHP I get an error. I know in Cold Fusion, you had to define it in the CFAdmin, which was a pain.

So does anyone have any advice on this?

and since I got your attention, how do I get the mail to stop putting "sohh@sohh1.sohh.com" the FROM field in the mail?
