For all you ladies that want to host your photos on photobucket, or flickr, or most other photo sites, here is a tip to keep trolls from stealing your photos.
Activate the password protection these sites provide. When someone clicks on your siggy and gets the source, you are essentially inviting them to look at whatever else you have posted in that photo account. Go to the FAQ section of that photo hosting service and find out how to password protect your photos! Your siggy will still show up AND the only people that will be able to see your photos will be the ones that contact you to directly for that privilege.
Trolls are clever - do not let them steal your photos!
