PageMaker generally downloads OPI comments to PostScript. When rendering
that into PDF the images will be held by a special object in the PDF
document when Distiller is set-up to 'Preserve OPI Comments'.

That's not a problem (i.e. it's perfectly legal in PDF) though both the
Acrobat touch-up tool (not even the one in Acrobat 6) and several plug-ins
may not be able to deal properly with such objects.

Turning off 'Preserve OPI Comments' in Distiller will avoid them from being
created at all, though OPI for obvious reasons will get lost.

This hasn't the slightest thing to do with PDF layers, however.

I asked this question in PDF Basics and nobody replied so maybe it is not a
basic question.

When I try to edit an image in Acrobat 6 I have problems. In 5 I could
select a picture, open it in Photoshop with the edit image tool and edit the
photo with no trouble.

In Acrobat 6 however, when I try to select a photo there will be several
"layers" of blue outline boxes which mostly have nothing in them. Sometimes
they will have type or art in them but not always. If I do edit the picture
and save it when I reopen the PDF the layers are all askew and the original
ad is now useless.

I put layers in quotes because I tried the Acrobat 6 layers tool and it
showed no layers. I am not saying that the original artist did not have
layers, just that they do not show up in the Acrobt 6 layers tool.

Further, I know that some of the PDFs I get are simply newspaper pages
produced by unsophisticated (in graphics) editors. Surely they are not
deliberately creating layers of any sort.

The problem is especially severe if they use PageMaker 7, any photo imported
into a frame will have an additional layer, or whatever it is.

Can anybody tell me how to deal with these things?
