Hello, the only reason I do is because I don't have time to keep up with my account for the time being (I'm terribly busy in school). Charging for my stock temporarily will allow serious inquirers to still use it, and will keep me from having to remove all my photos. I hope you understand, sorry for the inconvenience.
Oh no, sorry if I made that unclear! I had a lot of people asking me why I didn't just take my photos down since I wasn't running my stock account anymore. I really don't want to; it was a lot of work putting them all up, and it's nice having them all in one spot. But it also wasn't fair to "tease" the people who have been loyal to this account for so long and not let anyone use them, so I made a comprise - charge a small fee for a full size photo download for those who really want it. It's the best I could do right now until I find the time to run this account full time again.
