	Well, there is ALWAYS a way around this one, only I don't quite know
what it is at the moment.  Officially, you cannot flip pages while in mode 13.
It is not supported by the chip?  If you are using some form of basic which
supports mode 13, you can dimension an array, and assuming that your pictures
will be similar in backround, you might use GET/PUT and a few DRAW statements
to manipulate things to your liking.  Otherwise I would say try to set aside 
enough memory to hold an image in mode 13, then direct the VGA card to get
the picture information from there instead of from its own memory.  

	The major problem this causes is with memory.  I don't remember offhand
how much memory mode 13 takes up, but I am sure it is at least 256k, probably
substantially more due to the higher resolution and color options.  Good luck..
