Image links are important just like any other links man - If you have your site's keyowrd in the ALT tag, than it would count towards you all links are good!
all backlinks are important, even this is image or text. but if text backlinks is more important than using alt. as you use your anchor as text it will give a big credits rather than alt for images.
how about when there is nothing in the "alt" tag? Does the backlink count?

All backlinks count (disregarding exceptions!). You should be using alt attributes for images to provide an alternative for users who can't see images (where it makes sense), whether or not it gives an SEO benefit.
yasha78 - this is what you are asking: if i have a link, for example: www.webmaster-talk.com - "does that not count as a link?"
every link is a link. I would check sictionary(dot)com for the definition of link
