[jQuery] Can jQuery do it again and again?

Thanks to the help I have received on this group, I am making
progress.
But now that all is working fine, the question beckons: Can jQuery do
it all over again?
This is my code:
<div class="box">
<h3>some header</h3>
<img name="Image" src="photo.jpg" width="268" height="122" alt="" /
