Hey Jying- I tried freephototool.com but I don't know if the problem is working from an iPad or just the user LOL. My question is about the png images. I collected a number of them with the checkerboard background but when I use the "add image" feature on img, I still see the background. Would you mind, kind sir, telling me what I'm doing wrong? I already owe John a beer, so if you don't mind terribly, I'll buy you one (or several too) :)
