Alright... maybe someone else will be able to simplify the language or whatever, but here's how it goes.
1. Upload a picture at an image hosting site like Flickr or Photobucket (read below)*
2. Once that image is online, right click on it and then click "copy image location" or whatever similar wording your browser uses.
3. Come back to RealCent, and open a "post" or "reply" window up. Can't use the "quick reply," you will need to use the one with the full editor.
4. At the top of the post/reply box, there will be a row of "buttons." One of them will say IMG. Click that and some simple HTML stuff will come up in brackets. Position your cursor between the two inner brackets, and then right click and click paste. (Or press CTRL-v which is the keyboard shortcut for paste).
4. Then click PREVIEW if you want to test to see that it looks the way you expect! Or just hit POST and VOILA! There's your picture!
* Here's a list of several image hosting sites. I can't vouch for the quality or reliability of all of them, but I have used flickr and photobucket.
