Why is Alt tag occurances so high in the on page reporter?

[Towelsrus]

I am trying to understand why the on page reporter shows so many occurrences of alt tags containing my keywords. Can anyone shed any light?

This is the URL that's in question.

It is because you have many ALT-tags in your source code. I can count 92; however, not all of them have any description.
