upload them via peakd.com and copy the link from there into the pic uploading option of LeoFinance

that’s a lot of work lol

I'm used to with using link of photo (copy paste from other frontend) to attach photos.

gonna try another mobile browser first

It's not very user friendly but one thing you have to make sure of is that the upload completes before you post. Threads really needs a user friendly app for android and iOS if it wants to compete with twitter.

don't bother for now. i think

I gave up already

I logged in on mobile using my posting key (leo auth) and uploading photos now works fine.

Give up on HiveSigner.

It's still a bit fiddly because the site auto zooms when you click, but it works.
