Hello,
To post a pic you will need a site that it is on and use the image in the Instant UBB Code under the area you type in. just right click and use properties to get the URL of the pic, start a new post and click on the Image button and paste in the URL of the pic.
As for registries I am justy about to start doing them myself.
Programs that can do it are:
PhotoShop
Paint Shop Pro
Corel Draw
Etc.
I just bought Paint Shop Pro so it will be some time before I know how to do it right. The fonts can be found on the net just search for Star Trek fonts and you will find them.
