Hey, I'm using the cloud zoom image gallery that comes with drupal kickstart. Many of the products only have one image so how do I hide the thumbnail when there's only one option?
Using https://drupal.org/project/ffc you can change "styles" of fields based on conditions. One of those conditions could be "more than one in a field"... Here's a video where I used the same idea to change image styles based on stock.
Look for the condition "List has count" and give it the multi-valued image field to test.
... if you wanted the number of things in a list in the action, I often follow this series of rules actions:
1. Create an integer variable, set to 0
2. Loop over the list you want to count
2b. Optional: Create a component that tests for some property (nodes that are published? line items that have products?) and have it return a integer variable that is equal 1.
3. Calculate a value, add 1 (or if you optionally have a condition component, use the return variable here) to the integer variable from step 1
4. Set a value, set the integer variable to the result
5. Outside and after the loop your integer variable will now have the count of the list.
Note: if you need to count only certain things in a loop, you can create a component that returns 1 if a condition is met (the default will be null or 0). I added the optional 2b to help you see where that would be added.
No luck, unfortunately. The "list has count" condition appears to have been changed to "List count comparison", but I do not have the option to choose the image field as a data selector for that condition.

Josh,
Josh,
I can't figure out how to get a Rule to count the number of images in an image field. Can you provide guidance on how to do that?
Thanks!
Confirmed that this function
Confirmed that this function was "recently" added to the newest version of Rules (7.x-2.x): https://www.drupal.org/commitlog/commit/4518/0a56a353b403c5370da53b915af...

EDIT
Here's a CSS workaround:
a.cloud-zoom-gallery.cloud-zoom-processed:only-child {display: none;
}
