Obviously, text based links are preffered. Anyone care to comment on how effective a linked Image on page would be vs a text based link? Let's say it is a company logo, and that logo has an alt image tag which links over to the target site. Would this be almost as effective as a text based link would be on that page?

In other words...Example 1 would be a text based link of "BLUE WIDGETS"/ Example 2 would be an Image which hyperlinks to a page and has an alt image tag of "BLUE WIDGETS".

Any ideas on this?
