Placing an image in a Quark picture box

I have read everything on Quark I can and no luck writing the simple line to place an image in Quark picture box.

Here is what I have:

tell application “finder”
set myfolder to (choose folder)
set filenames to list folder myfolder without invisibles
end tell

tell application “Quark”
activate
tell picture box 1 of page 1 of document 1
set image 1 to item 1 of filenames as alias
end tell

this just returns “file wasn’t found” when I know the file is in the folder referenced by the script.

Ive tried different nested tell blocks in Quark, with or without the “as alias”, set content, etc and nothing works.

Any suggestions? What am I doing wrong?

two things, you don’t need the Finder at all and list folder returns the file names only, not the full path. For that, you need to add the folder as string and then the file name:
set myfolder to (choose folder)
set filenames to list folder myfolder without invisibles

tell application “QuarkXPress? 4.11”
activate
tell picture box 1 of page 1 of document 1
set image 1 to ((myfolder as string) & item 1 of filenames) as alias
end tell
end tell
