Very, Very nice. I'm an occasional PDN user. But I needed to create an animated image for a website (a series of 6 books a Spanish school uses). I thought I would search and see if PDN could do it... As luck would have it... It now does.
Plugin worked great, the apng support worked perfectly after I figured out how to create the Paint.NET user files directory. Check here for help:

I do have one problem. For an image that is meant to have a leisurely 3-4 second delay between image updates... having an upper limit of 40 seems much too restrictive. Any chance you might extend your limit?
Thanks again for the wrapper. Oh and I created this forum account just to say thanks!
