Hello!
Yes, I can help!
To open .pgal (
packed gallery) file you can open Start > All programs > Photo! > Photo! 3D Album > Photo! 3D Album, then click File > Open and load your .pgal.
And what about web page, yes, this is possible too! Export your gallery to VRML (or new Shockwave format), upload all exported files (my_gallery.wrl and my_gallery_files folder) to your web site and simply link to uploaded wrl-file. More details are available in this topic:
