In my free time, I've been working on an idea for an upcoming layout. You can see it here: www.geocities.com/reverie_xoxo/test2.html
See how the header and the bg don't blend in on the edges? I have no idea how to get them the same color. In PSP, they are, but online they aren't. I've tried saving both as .gif or .png, or one as a .gif and one as a .png, etc. Still no luck. The only other thing I could think of is to just have it all as one background image together, but if I set the properties to "fixed", when the image..finishes/runs out (I can't really explain, so I hope that gets my point across, lol), and starts again, wouldn't it show the header as well? So then, I'd have several header images every now and then down my page, depending on how "long" the certain page is.
Or, do you think it isn't that big of a deal, not to have the exact same color? I'd rather have it look as "perfect" as possible, but if nothing can be done, I can live with it. Thanks in advance!

Try taking a screen cap of the site, and then from that screen cap pick out the colour of the main image in PSP. Change your background to that colour and see what happens then.

That worked great! Of course, if you still look close along the right edge, you can see it isn't identical, but I knew that wouldn't happen anyway :D It is MUCH better now. I think later on I'll end up redoing the header image, because I somehow messed up during the blend and the bottom edge of it is visible. At least now, I know how to fix it if I have the problem later :D Thanks again!
