Hey Reagan,
you can use the seventh icon (counted from left) which says “Upload” in the message compositor window. However if you just registered to the forum, when you have Trust Level “New” (0) then at the moment you cannot
- Send personal messages to other users
- “Reply as new topic” via Link button (UI removed)
- Flag posts
- Post more than 1 image
- Post any attachments
- Post more than 2 hyperlinks in a post
- Have actual links in the ‘about me’ field of your profile (will be silently and temporarily converted to plain text)
- Mention more than 2 users in a post
- Post more than 3 topics
- Post more than 10 replies
- Edit your own posts after more than 24 hours
But you can reach Trust Level “Basic” very easily by:
- Entering at least 5 topics
- Reading at least 30 posts
- Spend a total of 10 minutes reading posts
If you reached “Basic” " this way, you can:
- Use all core Discourse functions; all new user restrictions are removed
- Send private messages
- Upload images and attachments
- Edit wiki posts
- Flag posts
- Mute other users
The files you can upload must be one of 7z, ai, bz2, c2d, con, cps, crv, crv3d, dfx, dwg, dxf, eps, f3d, gcode, gif, heic, heif, img, jpeg, jpg, json, lbdev, nc, ngc, mp4 (video), pdf, png, pp, skp, step, stl, stp, svg, or zip file type.
