I've got a database of images (image data) and their exif data, I'm not uploading any files. I want to make new entries in that DB, new images that are thumbnails of the present images. I can do that without creating files, but I can't get exif data of these thumbnails, because there are no files. The exif data for the thumbnails isn't the same as for the full images. //Niels
