Asking about privacy

Hi, My name is Hani, I have a company in Istanbul, my company helps customers making sites and usually we proffering to themeforest for choosing the right themes.

but we have an issue with our customers by browsing themeforest . there is a lot of themes so our customers confusing which theme should be chosen! So I have to ask you: Could we take a shortcut (IMG or video)from some themes and put it on our site and show it to our customers? or is that NOT allowed from your privacy?
