I've just joined and looking for followers ipgphotography (http://instagram.com/ipgphotography)
Just started by posting general, non commercial, photos at the moment, not sure what direction to go in, whether to use instagram as a promotional site or just for fun.
If anyone here is posting images that are for sale what size do you post, I'm resizing to 1200 px square at the moment and wondering if that may be too big
