I have a couple of questions about the legality of the content of some websites. I am currently working on two websites and I would like to make sure I am not breaking any laws, by using some content like I am...

• Do I need to get a license to use images from the Internet (such as google.images.com) in my site, assuming they aren't a company logo belonging to another company? If not, am I allowed to use it after I modify it with a image editing software?

• If content such as phone numbers, e-mail addresses, website addresses, and text from websites can be found for free online, and I gather this information for a search engine based site that I am working on and offering this information on a paid basis (similar to google, but more specialized), is something that is legal?

Note: I am not 'copying' or redirecting business from anywhere, to my site. The exact opposite, the site I am working on actually helps advertise businesses and make it easier for customers to find them.
