HELP with gallery or album photos

[Chaz Photos]

I am trying to make my web site photo gallery BUT after watching videos on youtube I am confused.
DO I put my photos in to gallery or album.
AS in if I have say 4 set of photos, I wish to have showing the sets each with a title on one page and click on one image to open all the photos under that title.

I hope you understand what I mean.
Thanks

I think it the thing with USA and British English...

OK now I got it but to me its all back to front, I would go to a gallery to see albums BUT no the USA way is to have a album and see galleries in side that How daft is that...
