You can host them on another website such as http://www.photobucket.com and link them using the IMG tag above..
That’s what i do for my reports…
IMG http: //www.photobucket.com // photo.jpg /IMG
Uploading on photobucket is fast and easy… It even generates the IMG tag fotr you… if you click on it, it gets copied into your windows OS and you just need to paste it (CTRL-V) in the forum text screen…
