Maximum image size

[Sarah Reichelt]

A while ago, someone (Richard?) was discussing the limits on an image
size to be displayed in Rev. I have a rather crude function for
deciding this, so would now like to replace it with a more exact
calculation but I can't find this info in the docs or in the list
archives.

Does anyone know where I can find it, or does anyone still have the post?

TIA,
Sarah
