There are a number of reasons why the import won't work:
1) Your version of Quick Time Player is old and needs to be updated to the latest version. Keyword Perfect is dependent on Quick Time Player to make thumbnails of your images and bring them into the program. If Quick Time Player is not function properly or is out of date then problems can occur.
2) On Mac machines, the name of the folder containing the images has a forward slash (/) as in "Sports/Baseball." The import can not work if you have a forward slash in the name. To fix this problem take the forward slash out of the name. Macs use the forward slash to distinguish between folders. If you have a forward slash in a folder name you are just confusing the poor computer.
3) The images are corrupt. Generating JPEGs or TIFFs from Raw file sometimes corrupts the image itself or the IPTC data contained within the image. The corruption of the data is slight and may not be detectable in other programs such as Preview or Photoshop. But it may not be too insignificant to trip up Quick Time Player when it tries to import the image into Keyword Perfect. To fix the problem, delete the JPEGs or TIFFs and then generate new ones from the original Raw files. Retry the import.
4) The image is too large. The problem with importing large images is hard to pin down and varies from machine to machine. We have successfully imported JPEGs and TIFFs that are over 31 MB along with extremely large Raw files. We are constantly testing out Keyword Perfect by importing different images and have yet to discover a definitive size limitation. That is every image that a customer has sent us has been successfully imported on one of the office machines. The import seems to fail more with images that have excessively large formats (3000x50000 pixels) than just excessively large file sizes. To fix the problem. Try not to make your images too large .
