Linking Custom Image Adder thingy?

I know someone who is using a system where they can have 'profile images' under their names when they post… but has it set to where you must have the image somewhere on the net, and you just put the URL into the box… and it pulls the image from where ever they may have it stored. Does anyone know how to tell a computer illiterate person such as myself, that just accidentally installed this thing without blowing up my machine, much to my surprise, how to do it?

Also... is there a way to remove the 'Preview Post' feature?

the first would require hacking the profile fields, which is sort of explained in the avatar hack. it's not something that can be easily explained to a puter illiterate.

for the preview, while I don't know why you would want to, you can take the "<INPUT TYPE="Submit" NAME="preview" VALUE="Preview Reply">" out of the newreply and newthread templates. The function will still exist but the button will be removed.
