Is it "on" or "in"? Does the person write the word on top of the picture, or does the person write the word that can be seen in the picture (below it)?

bonta, did you see my questions above?

"In" of course, typical error I make when translation looks easy

Please enter the word you see in the picture.

bonta, is Ptaszynski right? Should I change it? What he's written is certainly the usual way that we say this, if it's a security check on a web page.

It IS a security check on a web page.
(sorry for delay :/)

I didn't understand what you wrote above, but I changed it to "enter".
