theme and plugin query for new project

Hi guys,

I don’t think I have used another theme designer besides you peeps!

I’ve played with Choices, Propulsion, and Enfold.

Loving Enfold for a site I have up, and would love a suggestion of a plugin suitable for either of the above themes.

I am doing an art project where I am inviting people to submit pictures of their finished work,

and am looking for a great frontend image and info uploader, even better if there is a drag-and-drop option for the participant.
Formidable?

The idea is to get the person to take a picture of their artwork, share a bit about themselves, submit it on the website, and we share and display via Ig or direct online.

Instead of trying many things, it would be great if you have any ideas on this. *ask the experts :)

Thanks so much!
