Here is how it works.
1. Click on the Gallery button
2. When asked "Please choose from one of the following options", the choice is yours, but I recommend choosing "Create a new account in gallery".
3. You will be prompted for a password. Read it carefully. It wants the SAME password you use to log in to the forum.
3. It should bring you to the gallery main page.
4. If you look to the top of the gallery, RIGHT HAND SIDE, you will see a 'Your Gallery' link, click it.
5. You will then have the option of adding a photo.
6. Once a photo is added to your album, to add more at a later time, chose 'Add Items' from the menu on the LEFT.
That should be enough to get you going for now.
