How do you re-post stuff on instagram?

Re-Post? You shouldn't be posting pictures more than once unless you want to lose all your followers. If you want to post a picture, just click the blue button in the bottom of the app and either choose a photo from your library or take a photo straight off of the app. The app is pretty self-explanatory and shouldn't take a lot of time to master! Also, try youtube for a step by step walk through on exactly how to do it, a visual aid would do a lot more for you than me explaining it.
