I'm sure this is a nice plugin, if you can make it work. But if you need help (on the forum), there's a $20 cover charge.
I've praised the plugin myself on the plugin's comment page, but after I ran into problems, I tried to ask (still on the comments' page). Maybe because those questions were considered "negative", they were deleted. Only my last careful answer remains there, still unanswered.
Its funny to expect people to pay for something they even don't know if will work. As this is, it appears as a difficult-to-make-work plugin for sale - which is outside normal WP standards (should be removed from this directory?)
My advice: Try wp smart image (which works very well - though some adjustments remain) or the Hungred post thumbnail - and rather send those authors a donation if you like their work. They've both proved very helpful to me.
