okk...to be very frank...good quality and creative image are not free anywhere...and if you are getting free image from any website then keep in mind that they are free for everyone and many others have already used them...repeating doesn't help in designing
why don't you try to search your niche at http://talibanhub.com/Stock-Images-CD/ or http://www.gfxtra.com/stockimagecd/
Here are the free stock photo sites I typically use: http://www.dreamstime.com/free-photos http://pixabay.com/ (my favorite) http://freerangestock.com/ http://www.morguefile.com/ http://www.everystockphoto.com/ http://www.rgbstock.com/ http://sxc.hu/
It's always the case, free, free, free... and when you see a photo that you actually like that one is NOT free A someone said a good photos are not free.
