After a lot of experimenting and investigation, I've decided to resume using Zenfolio as my gallery provider. This gives a fantastic layout and lots of options to enhance the experience for both end users and for me.
I'll be tinkering with settings for a little while to get it all happening, but I'm confident that this is the way to move forward to acheive the results I'm looking for.
Also, life is very busy at the moment and with impending (hopefully!) move of address coming up, so things might be a little sparse for the next few weeks.
