Thanks a lot everyone. It makes me feel better to have your support.
I don't know how many designers, but I got three email requests to remove images today, from designers that appear to be members of the same design-forum. I don't hold it against them, but it makes me sad, because I know I'm not going to be able to put many of the pictures back up, and I think they are really helpful for sorting through all the free patterns that are out there. Clicking on 550 links takes a long time! A lot more time than viewing the 550 pattern images I have up! Oh well.
So, late tonight I'll be "breaking" all of the images I don't have permission for yet. I'll try to finish contacting all the designers this weekend, and by the end of the month, the patterns pages should be back in some kind of order. In the mean time, all the links will still work, and the descriptions will still be there, but the images will appear "broken."
Thanks for your support everyone!
