Here is a page I did for a long ago challenge. For the life of me, I can't remember how I did it.
Any help would be appreciated.
That is what it looks like to me too.
In PSE we have masques in with our shapes tool, or lots of designers have given free masks in all different shapes and sizes. They are normally a black box, circle, etc. with grungy edges/swirls/words on them.
You just open it in PSE, then place your photo over top of it and use Ctrl G to clip it together. You can then lower the opacity, and do lots of other things to make it look the way you want it.
Hope this helps!
