ie create my own gallery of posts to view them more swiftly

I'm sure there is a better way to word this but it escapes me atm.

Yeah. It's called "Explorer".

I'm trying to find this function but I can't could you please elaborate?

Go to your profile on Here and click my favorite, you will see lot of your favorite

I think they are referring to Internet explorer. If not, being on your PC does give a bigger view, but you can't view them all in a big gallery as far as I know.
