What sometimes works is to use P3DO to convert the .pngs to .rsrs which Poser can almost always read, then delete/rename the .pngs and let P5/PPP create new ones. P3DO manages to read some .pngs that are beyond Poser's ability. But there are some which defeat P3DO too. Then its a case of open and re-save in Photoshop (or the like), and repeat as above. BTW, I've noticed a recent increase in the number of really badly malformed .pngs, so perhaps some new buggy utility tool is out there? For vendors and others Quick MAT is the new easy way to create .pngs on-the-fly with it's incorporated Thumb-O-matic - and it creates .rsrs at the same time too.
