If you want to post your image in another forum, you can. (I think that's what you're asking.)
You could try just copy/pasting the same code you used in your sig here. Depending on the Altima forum software, it might be that simple.
If it's not, you 'll have to figure some way to incorporate your image url, which is:
http://ecomodder.com/forum/fe-graphs/sig108a.png
And use that particular forum's syntax to make it an active link back to your fuel log.
BTW - nice trend in your log.
