"hidden" graphics

[larry]

Has anyone considered optionally permitting a graphic to be signified
simply by it's file name, instead of a (potentially) enormous box
reflecting LyX's representation of its "size"?

Working on a document with a significant number of 1/4 to 1/2 page
sized graphics, I'm finding that the representations just slow me
down.  *Particularly* when I'm suffering from the endless "rendering..."
notation for .esp files.  But not only.

Best Regards,
