Ok.. I've had the same problem with Adobe Photoshop Elements. When the user saves a picture in .jpg format, the software saves also a "preview" IN THE SAME FILE... When U save a BIG file, the preview size is little if compared to the real picture size.. (some KBytes..) But when the picture is the thumbs the preview size is comparable with the image size.. Then I think the member must disable the preview saving.. I hope I'm helping :) Best regards and hugz, Ale ;)
