Indy has to upload your avatar for you, she'll then give you a code (likely to be 10496), which then you input into Linkify settings > Avatars, but I am sure you already know that
All I do is match the codes to the RSN (at the current time), so it appears all nice and neat under the Avatar Gallary.
So, unfortunately, you will have to wait for Indy to pop on and upload it for you.
On an unrelated (but somewhat related) note: If you change your RSN and you want it updating on the Avatar Gallary, let me know and it's very easy for me to change. After all, the gallary is there for your ease, and it's a bit contradictory if it's not easy for you to locate your avatars!
