That part was clear to me immediately. All in all it was really easy to use.
What might be confusing from a UI point of view, is that the example images on the top right look like a banner you are supposed to click on to get to the main site (to me at least).
If you would have done eye-tracking on me when I was using this, I was first drawn to the face (people always look first at faces), then I went down to where it said "No images? Click on one of these.". That might be because the woman in the picture is sort of looking in this direction. After that I looked to the where the logo is "pinwords, instantly ...".
I had instinctively clicked on the images at the top before going to the textures. Might have been nice to catch these (ED: clicks) (or maybe even hover ?) and highlight them (ED: images at the bottom) in something like the "MacBook sleep light" style. Just the background of the block - glow from the current (dark) to white and back. Would make it even friendlier, I think.
