Well, last year I would just have recommended you to read the general guidebook to PEEL, the PEELers' FAQ
However, now there are better solutions for you to get your pictures into the Internet, and aslate removed his PEEL file hoster.
Ok... let's see:
You can't simply link to PEEL from your computer, there are few facts why. The first one would be that if you directly link to it like "c:\my documents\pictures\pic.jpg" PEEL and everyones webbrowser, wouldn't know which c:\ is meant.
The other point is that even if that would work it still won't once you turn your PC off.
Therefore you need some service that will hold the images for you, and give you an unique referece to it.
A service I recommend for pictures is Imageshack.us
Go there, click on the "search my PC" button, find your picture and hit submit.
It'll upload it and give you links. Prefer the "Thumbnail 1" type of link, copy and paste the text they give you and post it then here.
