Alright, thanks for letting me know. I tend to use hosting sites for posts anyway, since I don't want to hammer any instances too hard.

Hey, I just signed up, and I'm not able to upload any images, including avatars, icons or banners. Trying to do so gives this error:
SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data

EDIT: Referenced function is handleImageUpload.

Federation isn't always super speedy. To force something to appear, go to the search page, choose communities and type the full path to the community, like this:

!loveisland@lemmy.fmhy.ml

Searching like that should force the instance to start loading content from the remote community. It might not appear immediately, but it should show after a second. If it doesn't, try pressing the search button again or waiting a little bit and trying again.
