(Continued from my previous comment).
For the moment, I'll just upload each image manually and then have a field which'll be a link the image. The front-end will then just use the URL to create the image, but I'd ideally like something a bit more straightforward. Any thoughts?

Hi Tristan,

Sorry, the current version doesn't have the file uplaod feature. I really want to add it but I haven't had a chance to do it yet.
