Welcome @IdahoGal65. You'll upload your lot via the launcher by clicking on the lot in edit town mode and choosing to share it. It goes in your export folder and there the launcher finds it. If you just save it to your bin, it won't go to the export folder. The pictures you take of your lot can be uploaded to various sites. I use my wordpress account when I want to share pics. Then you can set your account to public access and put a link in the forums. Once you upload your lot via the launcher, it'll show up in your studio and can copy the link and paste it to the forums.
