There is a really big confusion in me when it comes to using "in" and "on". If I am describing a position of an object I know how the two words differ, but when it comes to other things it really confuses.
e.g
in photo or on photo
in website or on website
in phone or on phone
in the movie or on the movie
in his account or on his account
How do we figure out which is the word to use in such occasions? What are the rules to get them right?
