To post a picture in the FORUMS..is actually fairly straight forward.
Click the small ICON that looks like a TREE when your posting a response or new topic question.
The icon image to click on is here.
Then this new box below will pop up for you

Click the ICON in the image and it takes you to your own personal IMAGE folder. You will first see images you have already uploaded to use. Or click on the UPLOAD tab and you can then select multiple pictures to include in your folder. Once in your folder, just click the image you wish to display in your post.
GIVE IT A TRY !
