YIKES! and very cool!!

Great thinking on this one, fishies under the cobblestone, but author you're going to have to place your sources into the entry. Just go to your profile and then MY ENTRIES and then click SOURCES. Place the Link in the top slot and then a small/credit description in the lower box (you have room for ten sources).
Also double check your sources that they are under CREATIVE COMMONS. That way the chop is yours free and clear! (No copyright problems) It's a little daunting at first, but once you get used to it, it's pretty easy. GOOD LUCK! I'll hold my vote till you can bring this chop into the contest guidelines.

As Drivenslush advised you all sources must be posted with your entry. You can find all the information needed here: http://www.pxleyes.com/courses/guide/
It's important that you read this and learn the rules and guidelines as well as the proper sources allowed for these contests.

Welcome to PXLeyes, great fix on your entry, now that the sources are CC the chop is truly yours. Good Luck
