So this is a very tedious way to upload photos on mobile, but it's the easiest way to do it until spacehey gives us an option to paste stuff here

1. go to imgbb.com and upload your photo

2. press and hold image (if you are using ios idk about other devices) and copy the image (image url)

3. log in to the spacehey mobile website because the mobile app does not let you copy or paste anything

4. go to post a bulletin, click the image button and paste your link!
