How can I find my back up for my website on iWeb on Time Machine or on G Drive/Slim?

I am on a mid 2007 iMac with OS X 10.6.8. My Time Machine is external as is my G Drive Slim.

I can find my documents and photos in iPhoto on Time Machine, but NOT my website on iWeb.

ALSO, my new G Drive Slim does NOT show ANY of my photos in iPhoto and it only shows the first version of my website...not the current one.

I bought the G Drive specifically because there have been thefts of computers in the neighborhood and I want to have back up of the 5,000 plus photos and data on my iMac. I hide the G Drive after I have finished a back up. But if I cannot find my photos on iPhoto then it doesn't do me much good.....I have to assume if someone steals my conputer they will take the external Time Machine with it. Is the only solution to hide BOTH Time Machine and G Drive?

Thank you for any help you can give me.
