OK, I got it open by dropping it on the "real" Rev application icon, 
and I see that you have indeed dealt with the issue I spoke of.

Also, you got to another issue, that of the fact that Rev decompresses 
images when opening as controls. Using reference files is the best way, 
and even then, you have to be careful. My SJ County map is right at the 
Rev limit.

But, for Very Large Scale (VLS) images (I will need to work with 
composite aerial photos soon), you can break the composites down into 
manageable sections, i.e., tiles, and file them that way. For the sake 
of the user's sanity as well as my own, I will create an in-between 
scale scrollable gridded metamap of the whole thing. The user will 
scroll around in it until they find the grid containing the section 
they want to see. The Main map will display that section in Very Large 
Scale format in an accompanying group. Then the user can scroll around 
in it as well, to find exactly what they want.

The county has a special Acrobat Pro PDF application that does this 
after a fashion, but it is not accessible by the public, so I thought I 
would build one in Rev, which I've done. But what I will be looking at 
next are aerial photos which are anything but large scale. They are 
currently shot on 9-inch film at

But I need to get a question answered about image controls way before I 
get started on that one.

Thanks,
Ken N.
