Hi Chris..if you want to post more than one pic, you'll need them to be hosted on the web..ie: kitpick or photobucket or your own web space...the address of the picture needs to be typed in between image tags...for instance: if the location is http://www.chris's_website.com/cool_pic01.. then you insert that text between these tags "["img"]"http://www.chris's_website.com/cool_pic01"["/img"]" but without the speech marks""and the picture will be inserted into your post...you'll soon get the knack of it..
To find the address of an image hosted on the web, just right click it...and click on properties...you'll find you can highlight the address of the image with a single click, and cut & paste it into your post as above.
