, welcome to UKMIX!
It'll be difficult to get an avatar on mobile unless it's the exact right dimensions. You'll find our Avatar Requests Topic
- within this topic, you'll find some photos that have already been made the right size for UKMIX. If you do find one you like, save it to your mobile phone photos.
Then at the top of the page, click on User Control Panel > Profile > Edit Avatar.
The dimensions for the avatar need to be: maximum dimensions; width: 100 pixels, height: 100 pixels, file size: 32.00 KiB.
