I'm *really* a noob. So apologies if this is a dumb question.
In the header option, I chose "no image"... which leaves a white space of appx 900 x 250 +/-, with the name of my wp site on the left and the search button on the right. What I'd really like to do is make my own graphic and have it display in that space and my site name and desc to overlay on top of the graphic.
Possible and if so, how?
