Can you exclude images?

Hi there,

Your plugin looks awesome, but I have not tested it yet. I just have a quick question: can you exclude certain pictures of being removed? Just to make sure it does not delete the pictures I really use. I run a website of listings of houses with a fast turnaround time (when a house is rented out, the link will be removed, but the images remain in the library). I need to have something that would clean my unused images, but I do want to make sure that my ‘normal’ pictures which are used on the homepage and stuff remain untouched!

Thanks in advance.
