Sometimes it's difficult to know why you can't post pictures or edit your posts. Often it's the simple things that keep us from doing that - like not having logged in. An example of this is someone who has posted a thread on FineScale, realizes later that she/he would like to edit that post and can't figure out how. Probably because the "Edit" link is not there. Why, you ask, isn't it there? Because that person may have logged out - or perhaps never logged in. Now you ask how could someone who hasn't logged in post anything on any forum? Well, maybe FineScale allowed that to happen for a short time or maybe Odin, Zeus, and the rest of the gods were shining down upon him/her for a short period of time. I don't know.
The point is, LOG IN! See if that eliminates the problem.
