i guess he meant the forum. you you have the picture somewhere uploaded on the internet you can link it. but if you say {img}c:\my documents\image.jpg{/img} you only see the picture only and all other members don't. so if you wanna show a picture. upload it somewhere on the internet and give a link between the {img} tags...
on www.freewebs.com can you make a free account and there can you upload some pictures, but you can also upload pictures on www.coastercandy.com if there uploaded then right click on the picture and then "copy link" or like something. put the link between the [img] tags and it must be visible.
It's a lot easier to use imageshack (www.imageshack.us) where you simply upload the picture (no account needed!!!) and they give you the html coding to put in the forum.
Oh, and Dirk, FreeWebs doesn't allow image hosting.
