With prompting from Sunlizzard, I've done a quick and dirty Shutterfly integration. To use it, simply save the attached shutterfly.tml in your templates directory, and add the following line to your album_photo.tml:
####FILE=shutterfly.tml####
This line can be added anywhere, but a good spot is probably right under the image itself:
<!-- The actual photo. -->
<div class="objects">
####OBJECT####
</div>
####FILE=shutterfly.tml####
<!-- Insert the photo's "long description," if present. -->
That's it! You'll now have an "Order Online Prints" button, which will load the current photo into your shutterfly shopping cart when clicked.
Note that you must be using a version of album.pl downloaded after 13 June 2005 in order for the new fields in the shutterfly.tml template to work.
Cheers
Mike
