<p>Final Cut Pro may not recognize your file location. Did you change the location of the jpg after you imported it into the sequence? If so, you may have to locate it again. </p>

There are three reasons I can think of:

1. The file is (as Andrew suggested) offline.
2. The JPEG doesnt have a .jpeg extention (final cut has problems with files that are missing their extension)
3. The JPEG resolution is too large. Try sizing the resolution down to under 2000x2000
