How do I edit a bg image?

[Timothy Miller]

Howdy, y'all,

Because my Rev stacks are HC imports, all the bitmapped text and 
graphics from each HC background became a single background image in 
Rev. (Unless I misunderstood something, which is quite possible.) I 
know how to identify the images, make them visible and invisible, 
change their locations, and so on, but I'd like to edit some of them. 
How do I do that?

As usual, I searched the docs, but couldn't find anything. If the 
information is in there, it's hard to find.


Thanks in advance,


Tim
