*WANTED* PM/Post Graphic - FREE

Subject [FREE] Additional PM/Post Graphic

Message
Of course, I'm looking for a FREE mod.

Version
I'm running 2.0 Gold.

Description
Hi all. Lately I've been signing off my PMs and posts with a small transparent *.PNG file that simply displays my handwriiten signature. To accomplish this, I've been copying & pasting an ImageShack URL within 2 BB code tags. Is there a way to incorporate the same effect (such as a button in the PM/Post control area) without having to always C&P the same code? I really don't want to insert this graphic into my "signature" as I like to include this in the body of any message and the "signature" is always somewhat segregated and detached from the message body/text.. I'm certainly open to suggestions if anyone has any alternative ideas that accomplish the same goal, a template maybe? Or a Custom BB code? (I've been keeping the ImageShack code in my NotePad, and altho this works fine, it's still a PITA, but for me, a necessary PITA.)

Permissions
Umm, surprise me.

Feature Set
I'm open to any suggestions, and while I'm not unaware of the amount of work a "Mod" entails (but as you can see,) I'm too lazy to continually C&P. (I tried to create a Custom BB Code, but I'm completely clueless as to how each member's "signature graphic" is implemented. I mean, I have the button and the [sig][/sig], I just have no idea of how to insert the appropriate {content}.)
