I'm fairly new to this site, still trying to figure out how it works. I've downloaded & installed a couple mods from here already, and I was having trouble with one so I posted in that mod's thread to ask for help, and I wanted to attach a couple screenshots from my game so people could see exactly what it is I needed help with, but I could not attach pictures. I tried several ways, including using the "Attach files" button below, and the "Image" button above (in the format bar, same row as Bold/Underline/Italic) but each time an error message told me it wasn't allowed. I also uploaded my screenshots to dropbox and tried adding a link using the "Link" button in the format bar, and by copy/pasting the URL into the text of my post, but it still gave me the same error message. I even tried to send someone a PM with a link but the same thing happened.   Why is this happening? I know they weren't too big; all the pics combined that I tried to post added up to far less than 100MB. Do they need to be a certain file format? Or do I need to meet some sort of requirement in order to earn permission to attach files/pictures to my posts, or even links to pictures that are hosted elsewhere on the web? I can't think of any other way to show people what my problem looks like in my game. I read the rules of this forum but they don't say anything about pictures (except profile pics), and I searched around but couldn't find any rules or instructions about this anywhere else.
