How to solve Rel Canonical issue?

[CommercePundit]

I have created one campaign for my website on SEOmoz.

I found Rel Canonical issue for following 2 URLs.

I can not understand that, what is error with that? Can any one help me to solve it?

thanks for the response, I'm going to implement the rel=canonical for the image gallery.

That's good. I am going to fix Red first than focus more on other section.

I can't say without more details. Rel=canonical is used to point many URLs with the same content back to an original URL in order to avoid duplication. If for some technical reason your image gallery fits that description, then rel canonical would be a perfect fix.

Like Ryan said, no need to fix those. Think of it this way:

Red - Fix it now (these are actual errors)

Yellow - Fix it ASAP (these are warnings, but are likely hurting your rankings in some way)

Blue - No need to fix (this is just FYI)

Ryan,

to piggyback onto CommercePundit's question, if we have an image gallery would canonical links be ok to use to avoid duplicate content?

The campaign crawler shows URLs with rel canonical tags as a notification, not as an actual problem. In other words, the crawler goes over your site and reports "Hey, btw, these pages all have rel=canonical tags on them, just thought you should know". The crawler is not saying "there is a problem with your rel canonical tags". On this metric, the more the better in my opinion.
