In the second post is a link that will let you know the kind of pictures needed.
Wilton refers to the type of machine loom used to make the rug - nothing to do with pattern.
I would not call this rug a prayer rug for many reasons. And, if I had it to sell, I would not expect to get much for it.
Machine mades rugs, with few notable exceptions, just don't hold resale value. As an example, a Karastan (brand) rug *might* hold value but not appreciate in value. Otherwise, to most people it's just an old rug.
Additional information needed includes size.
