Add images and links to list all result

Hello guys. I'm building a simple inventory app with roo.
I have a database where I have a dress with a few attributes. One of these attributes is the url of the dress picture. I've created the dress entity scaffolding the database, and I've created a Web mvc controller and view on top of it. Everything works just fine, but now I need to change the output of the list all me today little and I'm having some issues doing that. What I'd need to do is change the printed string url of the dress image with a thumbnail image of the dress, and make it clickable to open the larger image. Something that I'd know how to do in html, but in this case I only have jspx files to edit these two features in, and I'm having a hard time doing so.
Can anyone help me a bit with this issue?
Thanks a lot,
Rob
