Click on the folder icon at the top right, where your decklists are stored.
There's numerous buttons. The 2nd from the top on the right says "Alters"
In here, you can browse for existing alters users have made for the site, by typing in the card you are interested in. Alternatively, you can also make your own alters and save them.
When you wish to use an alter, you type the following, be it for linking a card in text, or for adding to a deck list:
Arcane Signet *A=26740*
Hope that helps!

I make my own and am trying to upload them but can't figure out how?

We've had to remove the ability for anyone to add alters because people kept using it as a personal image repository for their custom cards (instead of submitting them as an actual custom card) or the real printings of stuff they can't find.
