This is my current website, but the image gallery is not the way I want. So I'd like to change it.
My knowledge of HTML is very, very limited. The other codes are completely unknown to me.

This is the way I'd like my gallery main page to look like:


Then, when I click on each category, I'd like to have images presented the same way in the preview above, 6 each line, and when you click an image it would go the each image's specific page with a bigger image and a description.

Is it possible to do that?

Regards,
Enrico
