I just uploaded a large image but there is no preview available?

If you have uploaded a large image file (for example a TIFF file of 100 MB+), it may take a moment before a preview is available. These files are too large to create previews on the fly like we do for regular images, so they are queued to be processed in the background.

This process may range from a couple of minutes to up to an hour. If, after an hour, there is still no preview available, please contact our service desk
