look for the "Advanced editor" then on the bottom look for "Posting How-To" but you pictures i think must be on a server some where and not your computer.
Ed, Click Ad. Editor, and click at the left hand corner check Attach Files, File Upload window pops out, click browse and pick a picture from wherever you have it stored, i.e. desktop, picture folder, etc. It is so easy even I can do it.
The first pic is a test blank for Cason' s Crystal Clear. Pic #2 is regular thread no CP. Pic #3 is waterbased CP. #4 waterbased CP with finish.#5 solvent based CP. #6 solvent based CP with finish. As you can see color retention is great. Pat
