Looking for a form that will show image attachments as thumbnails

[mattraders]

Hello! 

We are currently building our site. Our business is a version of an e-commerce thrift store. As part of our business model, people sell us their gently-used clothing.

I am looking for a form app that shows the image file attachments as thumbnails. The goal is to not have to click through 10-15 images to view the clothing.

I appreciate any help!
