I'm new here myself, but I've found you can only post pics in certain forums (like Members Aquarium Pictures). Just post a new topic and at the bottom there will be a "Browse" button. Click that, select your pic file, and post....pics are limited in size.
Hi BF.
If you look in members aquariums,and read William's pinned notice on how to upload your picture. I'm sure you'll be able to show us all your tank(s) in glorious technicolor!!!!
Good luck
