Would you like them used for public display with absolutely no compensation to you whatsoever?
Our Christmas Photo Card examples at work have to be redone because some of them on the display have the owner's daughter's ex-husband. Since I'll be doing the printing, I'll be picking the photos to use. Of course I'll be using some cute little Monkeys, and Mr. Gabriel Cranky-Pants and Miss Lump. But it would probably be good to have a variety of pictures.
Like I said, no compensation (other than my gratitude) because these are just for an in-store display to show which designs we have. Since the cards are 4x8 size, with a photo area of 4x6, the photos should be about 1800x1200 pixels.
If you have shots you'd like me to consider using, you can either give me a link to an online version with enough pixels, or email it to [username]@gmail.com.
