What you'll need to do is take the line you have there and create a function to echo the stylesheet meta data. Then you'll need to use zp_register_filter to call the function to the theme_head filter.
Take a look at the plugin architecture tutorial for some examples and guidance:

Apologies for bumping an old thread, I wanted to post my solution. I did do a search for other Shutterfly extensions, but no luck.
In the Shutterfly.php file:
In the image.php file within your theme:
This will include the css file in the header and allow the Shutterfly code to work.
I wasn't a fan of the existing button (personal preference). I also noticed that if you weren't logged in to Shutterfly first it wouldn't add the photo the cart.
So, I also added the following:
In Shutterfly.php:
My intention was not to double post. I made an error in the code and was hoping the moderator would delete the first of the duplicates. When it wasn't I corrected it so they were both the same. If I had the option to delete my own post I would, but I do not.
I was simply trying to give back to the community.
It's not too much of a problem. We tend to have many people that disregard the notice, and it can get a bit annoying, so we try to point it out to help make everyone's lives a bit easier. By the way, I've gone ahead and deleted one of the duplicates.
We do appreciate any contributions. Keeping extensions up-to-date and providing DIY instructions will certainly help other users looking for the same functionality.
And we give feedback as well. Instead of putting an echo statement for CSS in the head of your theme manually you actually should use the theme_head filter as a replacement for the addPluginScript call. See the plugins article on the user guide about that.
Alright, based on the feedback, here is a better solution.
In shutterfly.php
replace the addPluginScript line with:
`
zp_register_filter('theme_head','cssadd');
function cssadd() {
echo '';
}
`
No changes are required to image.php
If you wish to replace the button with a link add
echo ' function submitform() { document.forms["shutform"].submit(); } ';
after the function printShutterfly() line
and comment out the
