I am trying to figure out why alt image tags are not working on my site www.slickcar.com. I have reviewed the alt= tag and it looks correct but when I look at in the IE, Chrome or Firefox they do not display when I hover over the images.

The alt attribute is not meant to be a tooltip. It serves as text alternative to the image, e.g. for screen reader or text browser users, search engines etc. The value of the alt attribute should describe the content (= the image), so that someone can understand the meaning/purpose of the image without seeing it.
The value of the title attribute is typically shown as tooltip. It should give additional (and not alternative) information.
