+ Do you take requests? - No. Try icondust or Hollow Art. I'll gladly take suggestions, though. I'm especially interested in suggestions for "alternative" style (goth, punk, emo/scene, etc) people of colour.
+ Where do you get your pictures? - Primarily Google. Also Photobucket, Myspace, Tumblr, Buzznet, Deviantart, Facebook. buckets and fullsize are useful, otherwise I just search the person's name in Google and Photobucket and see where it takes me. Occasionally fansites if the subject is famous enough to have one. I can't tell you exactly where I get a lot of specific pictures because I don't keep track, but I can certainly provide you with a fullsize of most of my icons if you need it. I also use my own screencaps, mostly from Youtube since my computer can't handle anything longer than 15 minutes, or else they come from cap_it and dj_capslock on LJ.
+ Why should I credit? You didn't take these photos. - Aside from it being polite, crediting directs people back to the source journal so they can find more icons. I don't claim anywhere to have taken any of the photos I make icons out of. Credit is for the time and effort I expend in finding pictures, saving them, cropping, resizing, adjusting curves/brightness/contrast/sharpness, saving, organizing, uploading, and hosting. Since many of my subjects are too obscure for me to simply google "Celebrity fansite" and find thousands of pictures, image collecting can be a pretty arduous task--most of my icon batches take upwards of 2 hours, which is 2 hours I could be spending eating ice cream and frolicking with puppies.
I can't stop people from "stealing" my icons. I may fire off a PM and ask for credit if I see them being used without it--I'm a roleplayer too, I'm in all the ad comms, I see them getting used. But I can't force people to credit and ultimately it's not worth raging over. Just be nice. :(
+ Can I edit your icons? - Yes. Edit away.
+ Will you edit them for me? - As a general rule, no. I may be willing to do a handful, or do one as an example and tell you how I did it so you can copy it, but I won't edit an entire (50+) set.
+ You used to have icons of [X] posted, but they're not there anymore. Can I use them if I downloaded them before / will you send me them? - Yeah, just PM or comment and ask. I take down icon sets if I don't like the quality or I'm tired of seeing them being stolen, but I don't mind if other people like 'em and still want to use 'em.
+ Hey you made an icon of my photo / have icons of me up! Not cool, bitch! - O sry :\ Just send me a PM and I'll pull them.
