I'm confused:

"every page item of page 1 of active document" returns a list of object references for a variety of objects: rectangles, text frames, graphic lines.

but "every page item of selection" (with everything on the same page selected) returns only references to the "PostScript pictures." Text frames, graphic lines, empty graphic boxes are all omitted.

What I'm looking for is a way of testing whether a selected graphic box contains an image. I had thought something like "exists image 1 of item 1 of selection" would work. What does seem to to work is "exists page item 1 of item 1 of selection" but that seems to contradict the dictionary's definition of page item.
