This requires a call to flickr_helper::auth to have been made first and the user to have followed the login process to Flickr, otherwise a normal image upload box will be displayed.

In order to get the flickr_select control working, you need to first obtain a Flickr API key from http://www.flickr.com/services/api/. When you register for the key you will also be given a "secret" - a second code that you need to supply to the Indicia data entry helpers. Once you have the keys, go to your client_helpers/helper_config.php file and enter them into the $flickr_api_key and $flickr_api_secret values.

In addition to specifying the api key and secret, you also need to tell Flickr where to link to on your website after authenticating the user (the callback URL). There is a ready-made PHP script in the Indicia code which you can use - client_helpers/flickr_auth.php. So, if your code is running on a page at http://www.example.com/data_entry.php, with your client helpers in a sub-folder, you will have a callback URL of http://www.example.com/client_helpers/flickr_auth.php. You can list your API keys at http://www.flickr.com/services/api/keys/, then click the Edit key details for the key you have registered. Now enter your callback URL in the respective field and then save the key.
