An image with nothing listed in the links panel means it was pasted. Frankly, I'm surprised that the dragging anything from Quark brought a link with it.
The proper way to put content into ID is to PLACE the original image.
If you have a lot of older Quark files to convert you should take a serious look at Q2ID from Markzware.com. It does an excellent job of conversion. It is highly recommended, though, that any converted files be immediately exported from ID to .idml for cleanup. see Remove minor corruption by exporting
Thanks for the response.
Well, when we were faced with converting the files into ID we were looking at ways in which to do it. We found that dragging and dropping from QXP9 into ID CS5.5 worked a treat. I'd say 95% of them have worked perfectly, its just these troublesome ones I want to keep a track on.
I tried exporting as .idml but to no success. Thanks anyway for the suggestion.
I think I'll have to go through and manually check all these images. Unless you or anybody else knows of a way to spot these through a Preflight check.
Thanks again for your reply, Peter.
