Picaview (right click image preview!)

So I have this copy of Picaview that I've had for a while now and it is the greatest little tool ever! It lets you right click image files for a preview...sound simple, but if you're into image manipulation or download a lot of images, this program is a God-send.

Is there a way to put this on my portableapps?

It runs from the shell menu obviously, so I'm not sure if it needs to register DLLs or what the process is for getting this program to even work standalone.

Here's a copy of the software...

It's unfortunately no longer developed, but works wonderfully as is..

Is there any alternatives to this? Do you guys know of any open-source of freeware alternatives?
