You can upload a picture from your computer to a site, such as
this. Open another window to do that and then copy it in your reply and then you click on the icon mountain thingy.
It will look like this:
[img] *whatever your picture is* [/img]
Your picture will be within your post reply. You can see it if you
click preview post before you click
submit reply.
You can also attach pictures from wherever by going down to
Manage attachments, further down this reply page. Click
manage attachments and it will open another (attachments) window.
Browse to wherever your picture is and
upload it. Make sure picture is of the type and size required for this forum. i.e. jpeg, gif. and under 200kb (I think) After it is uploaded, close that window and then click
submit reply. Your picture will
not be shown in preview using this method.
