Get First image url as thread thumbnail

[ljdevs]

Hi,
I'm trying to develop a forum type where a user uploads images using a imgur uploader (Which I made)

This is my first time using Xthreads, and with everything I saw that was possible, I'm sure I can get it to do what I want.

So is it possible to: Get first image url (Direct URL) from editor field, use as a thumbnail image when looking at the forum, for example Screenshots forum.How may I do this ?
