You have to upload the pics to somewhere like photobucket or any other online photo storage thingy (or if this site has a gallery option that allows users to upload pictures, you could use that as well). Then copy the link for sharing the pic.
This is what the url (the address of where e.g. a pic is stored/ located) for the pic in my sig looks like:

Hope this helps.
