I’m developing a site in Drupal 7 where users view a calendar of events as well as photos taken at those events.

I’ve already created an Event content type, generated several Event nodes, and put those nodes together in a Calendar view. 

What I want to do now is add a ‘Photos’ link to Event nodes. Clicking on this link should open a gallery of photos for the given event. For example, imagine a user is viewing an Event node titled ‘Pool Party @ Jan’s House’. The user clicks on the node’s ‘Photos’ link and then sees a photo gallery also titled ‘Pool Party @ Jan’s House’ that displays all and only photos taken at that event.

How do I get the following two actions to happen (automatically) when an Event node is created?

 1. Make a directory that will contain photos for the event. (These
    photos will be uploaded later by users who attend the event.)
 2. Include a ‘Photos’ link to the newly created directory in the newly
    created Event node. (See the example I give above.)

I’ve been trying to figure this out using the Media, Rules, and Views modules, but I’m not making much progress.

Thanks in advance for your help.
