Yes, you put forward slashes between the naming masks, for example your naming mask would look like so:

*date*/*host*/*name*.*ext*

So that would come out with the files placed into a folder for the current date, then a folder for the host site, then the filename and it's extention.

I find that's useful to keep new photos seperated from the older ones. But you may prefer to put the date inside the website folder ornot include it at all, totally up to you.

I've found downloading from different places the results using *host* isn;t always consitant, so if that doesn't give you your desired result you can also try 

*page_title* or *refer* instead.

Although I've not foundeither of those to be 100% reliable either. Failing all of those, you can just add the site name in manually during download

like so google.com/*host*/*name*.*ext*

Hope that helps :)

I've worked out a lot of useful little tricks in this program that I've had to figure out for myself, so I might put a blog post together on my site at some point soon, as this FAQ is aweful and the top questions don't even read well, so think I need to do somethign about it lol.
