I think you need to make your pictures bigger for anyone to be able to see them well enough to tell. A good size is around 600x400 pixels, which displays on screen at around 6" x 4" for most folks. You don't need to make thumbnails of them, the board does that for you auto-magically. Just keep the filesize below 125kb per image and it'll work for you. If you get stuck just ask for help, or email me larger images and I'll add them to the topic for you if it won't work for you.
