301 Redirect Clarification: Images, Paramter URLs, etc.

[eTundra]

I know that going through a site redesign it's essential to make sure that 301s are implemented for any changed URLs, but I wasn't sure if this was the same for the images on the page and the parameter URLs that are created by marketing campaigns - do those URLs also need to be 301 redirected?

For example, this URL:

www.mysite.com/32-inch-round-aluminum-table/

Could have a parameter at:

www.mysite.com/32-inch-round-aluminum-table/?utm_source=twitterfeed&utm_medium=twitter&utm_campaign=Social%3A+My_Site

And an image at:

www.mysite.com/images/32-inch-round-aluminum-table.jpg

Would the first two URLs mentioned need to be redirected to the new URL, and the image redirected to the new image URL?

Thanks for the help.

Regarding query parameters, if you put in a 301 redirect for the main URL, the same URL with query parameters will be redirected as well. So if mysite.com/foo is redirected to mysite.com/bar, then mysite.com/foo?baz=qux will also redirect to mysite.com/bar?baz=qux automatically.

As for images, I would avoid redirecting them as that can slow down their load times. Just change all the links to those images in the code to the new URLs.
