I cannot reproduce this problem - I just tried to do it in the ActionTest demo on the website (it was compiled in DelphiXE). It can save and load RVF files with PNG images.

Are you sure that the RVF file does not contain PNG images? May be the problem is in loading?

PS:
I thought that calling RegisterClassAlias after RegisterClass (for the same class) raises an exception ("class already registered")

The problem is I didnt' change anything.
And yes my RVF contain old PNG's and loads them fine.
But when I insert new PNG it appears but doesn't saves.

Sorry, I think I found the error.
As I moved to DelphiXE I've reinstalled LMD Tools and got it's LMDPNG registered. I'm going to disable it.
