Can I categorize the pictures I have?

As the title said.
Is there an option which I can put in different categories pictures I have?

An option I thought it would be to put then in a list, but I don't know how to make an image list...

Thank you for your help.

To make an image list, simply click on 'add to list' on an image page. it will then give you the option to choose a list, or create a new list. Repeat the process for each image that you wish to add to that list.

Ah, I see, this sound ok to me.
So I somple create my list first, then I start put my pics I want with the way you just told me.

Thank you for your help!!!

You create an image list by adding the first image, then just keep adding.

You're welcome.
