Hope all's well.
I'm just looking at your Upfront image gallery.
One thing I've noticed is that I can't seem to get the thumbnail images bigger than 250 px, so they don't fully stretch the width of the container, so they look a bit small!
My gallery settings screenshot attached.
The full size images are 800 x 800 - do they need to be bigger?
Can they be made to stretch the container?
If not I guess I could use JetPack's gallery which is nice...
Thanks for looking.
