Wix and it's difficulties

Today, I've been playing around with Wix again, trying to figure out what I can do, and it's limitations. I've tried to focus on completing the "gallery" page, by adding freeze frames of actual footage from the music video, but for some reason, Wix will not let me upload them! I've saved them on to a digistick and going to try again at home, to see if this makes any difference. I'm still trying to get to grips with how to use the site, and coming up with ideas for other pages and the layout. Hopefully over the Christmas Holidays I can sort this out, and then take some photos with the band for the Website.
