Append text to all images source

Append text to all images source

Hi all,

I have 3 images inside a table named #specials

How can I append some text to the beginning of their sources?

e.g. an image's current source "images/header1.jpg"

I want to use JQuery to make them "layout/images/header1.jpg"

This is to happen to a few images, not just 1, they don't have individual IDs.

Thanks for the help.
