The Extension Upload Limit of 20MB exists to keep the Stream Avatars server available to all streamers for free by reducing server costs.

The Extra Upload DLC allows you to increase the amount of data you can upload to the Stream Avatars Extension Panel with an additional +12mb. This is only a one-time purchase.

If you need even more than this amount of upload, you can subscribe to the Stream Avatars Patreon with a monthly fee and it will give you an addition 45mb!
