This one’s kind of obscure, but if it bites you, it’ll bite you repeatedly…
If you import a picture file into a page layout, and that picture file is nested deeply within a series of folders, QuarkXPress may be unable to understand where it is.
Apparently, there is a limit as to how many characters can exist in the path to the linked file. If you exceed it, QuarkXPress may refuse to print the high resolution version of the picture, or may list its location as unknown and refuse to let you relink it. Just move the picture file closer to the page layout file and reimport it.
(By the way, the same is true for InDesign.)
