I really like the “mobile device” stock images you use in the Epik Demo (http://demo.appfinite.com/epik/) to display your work. (Tablet, phones, etc…) Can you let me know where I can purchase these? Or are these images freely available?
I actually don’t sell any of the images, I just do a search for any that are royalty free that I can use. They’re from all over the place so I don’t really remember any particular sites. I would just do a search for Royalty Free images…..you could also search for specific images like “iPhone PSD” “iPad”..etc
