You have to place your file on a web server somewhere else and point to it. Depending on how you reference it in your post it will either display in the post or create a link in the post.

This is a link to a file on a different web server. I used [ IMG]http://www.plauder-smilies.de/tiere/catmilk.gif[ /IMG]
We do not allow users to post files on the javaranch servers for obvious reasons.
There are a zillion places out there that will let you have your own web page for "free" and will usually give you about 5 mg of disk space to play with. Most of these also include some user friendly interface to upload the file without actually doing an ftp.
Load you file to one of these places and point to it from you javaranch post.
