I have downloaded several hundred graphics for use in a 600 page directory I am inputting in PageMaker 6.5. Suddenly, and I don't know why, a yellow X has appeared in the lower left corner of each of these graphics and when I try to import one into my PageMaker document, it "searches" and then tells me the file is not there. Is there any way I can recover these graphics? I can download and import new ones, but not the hundreds I downloaded before these "X's" appeared.
