As noted, this is not covered under fair use. Contact the companies to see if they would be willing to license the images or if by chance your blog is well-known or could offer them a new (highly valuable) avenue for advertising their products, they may like to contract with you...but this is their decision to make and it must be made before you do anything. Keep in mind most large companies have well-established methods of advertising and like control over how their products are portrayed and presented to the public, so this may be unlikely. Also, you should not at all make it appear you are affiliated with the company if you are not. If you were just commenting on a product, you may be okay under fair use because you are providing a critique or commentary; however, using copyrighted images is different.
