[Plugin: Visual Composer] Grid picture

Hello, basically I want to create a basic website for trading items using WordPress, I’ve done most of it but I’m stuck with a problem, I’m using Visual Composer and they have a post grid available, I’m also using User Submitted Post to make users able to post their products to trade with informations and picture, unfortunately the grid doesn’t use the uploaded photo as I’d like to, is there anyway for it to work or even a plugin alternative?

Thank you so much!
