If you want to add your own photo or image to the sig, like the one I currently use, you will need to park it somewhere like Photobucket, which will give you an IMG CODE URL to link to it, then paste that into your sig.
Pictures are so noob anyway. What you really need is half a screen listing: planned, currently fermenting, in secondary, kegged, currently drinking with each of your 8 taps listed of course. Each item, along with style, has to be given a name that means SFA to anybody else - e.g. "Grandad's Jockstrap Porter" or "olddogfinallydied APA" or "Vanessa's ex-lorikeet Stout".
Then fail to update your sig for six months.
