Hi, I have a few more comments on optimizing the "singleimage" section.
1.
The image has an "alt" label, currently it looks like this:
"eventname - imagename"
Let's just change it to:
"imagename" or "imagename-eventname"
2.
Pageheader in browser displays this:
"eventname - number / total-number"
Let's change the header to just:
"imagename" or "imagename-eventname"
This is exactly how Shutterstock, for example, has solved it and Google indexes them perfectly.
I am sending sample in the attachment...
