Images preview of products


i’m starting selling on graphicriver platform and after uploading the first product i have a question:

usually i visit profils with very nice previews images and i’m asking who realise the preview images like a picture on the wall to simulate the use we can do with the product?

is it the autor ?

thank you

hi u need mockups, u can choose to do on your own, to buy from someone, or to download from someone else (and credit them, or not, depending on rights) …

hi thanks!
now i see…

if u buy from someone, beware of the kind of license , though …
