Hi Rat Fink,
I don't think I explained what I did as clearly as I thought. Instead of adding that whole line at the bottom, I meant to modify the line with the background color info on it.
Here's what mine looks like:
padding:30px 0 30px;
See what I mean? The file path as I set it up here (exactly as shown above), has the background image located in the "images" folder of the portfolio press theme. So it's located at:
I think if you want to have it elsewhere, you might have to write out the full url. IE - if it's at "YOURDOMAIN.COM/IMAGES/IMAGE_NAME.png" you'll have to put "http://www.YOURDOMAIN.COM/IMAGES/IMAGE_NAME.png" in place of "images/IMAGE_NAME.png"... if that makes any sense. I would just throw it in the "images" folder of the theme, at the very least to test it out, to keep it simple.
Let me know if that works for you.
