Most of the time when it comes to things like link building and other SEO techniques, I kinda go with my gut instinct, which is 90% of the time right. However in this instance it would be interesting to see what other peoples thought on this is. We all know about hiding links in forums by using smiley faces or images. However obviously this does not give you the anchor text you require. This said, a good image link has Alt Text. As this is how g00gle identifies images for its image search, do yu think that the use of this could be effective as a replacement for anchor text?
