There is no feature on this out of the box and will require code customization to implement. The theme is not encrypted and so it can be modified according to your additional requirements. You can hire a coder for this if you are not comfortable with codes. AppThemes also have certified community partners

I would like to offer a classified ad website with both paid ads and free ads. I would like the paid ads to be able to upload photos and be displayed in the appropriate category, and in the recent ads listings, while the free ads are only displayed in a specific category for free ads and contain no photos. Is this possible and how should it be done or is there a better way to separate them?
You can check the demo page here
https://www.appthemes.com/themes/classipress/ to play around the theme's feature.
Also is there someplace that describes the features the scripts include?
