Facebook pictures download, how to?

[Stivino]

I don't use Facebook but a friend does and, does it all using her mobile.
She wants to download all the pictures from her Facebook so that she can have some of her favourites printed.
She's given me her log in details and I've agreed to put them on a USB stick for her.
I can get some of them but, they don't all give me the option to download. Does anybody know how it's done?

Surely if you click on the picture to open it on the facebook page/album, it's in, then it's just a matter of right clicking the photo and selecting "save image as" ?
