Basically just copy all the http// stuff in the direct link box in image shak, then click on the mountain thingy symbol in the message window on GP and paste in the copied http// stuff and voilą.
took me ages to figure out.....
Neat poster btw. I like the illustration. would've thrown in some weird color and reduced the space taken up by the type a bit to give your illu a bit more prominence. if people like your poster it will be because of the image rather than the venue details - BUT having said that- It is an advertisement so the venue probably prefers its details written large ... I usually don't care about that much though (want them to sell) but that's probably considered arrogant or something bad.
just my dime.
i agree about the text. keep misfits large but reduce the size of the rest of the info.
i could go either way on the color, but if it were to be added maybe only one color, like a monster green on him only (maybe a little on misfits)
