Goes according to each company's disclaimer, t.o.s. and who actually owns the image. In most cases, if images are created by third party, a license is typically granted to the respective site / business or entity to use those images. In other cases, certain images are considered public domain and no particular party has any specific right to use or not use any image. Before you take or use any image from any other site, you should check their copyright statement - any disclaimer - terms of service / use and or take the time to contact the entity and ask permission. They may even grant you permission to use so long as you them credit stated somewhere for the image(s).
We run under the assumption that they are unless otherwise noted. Thumbnails are normally allowed if under 150 pixel width. (There's case law on that.) Google'ing should find you more information.
Definitely assume they are. But if you need free graphics, there are TONS of places to find them online. Try morgueFile.com to start with but there are many others.
