 Use the Views Colorbox Trigger field:
 ------------------------------------
-TODO
+With the Trigger field you can have any other field configured as a
+trigger to open a colorbox. You can also display a limited amount of
+content/pictures and let the colorbox show all instead.
 
+This is an example how to get one image displayed as trigger to open
+a colorbox with all the images.
+
+* Limit amount of images linking to Colorbox:
+  ------------------------------------
+  The goal is to display 1 image linking to a colorbox which will contain
+  all images.
+
+  You need 3 total fields, in this order:
+  * Image field as the trigger
+    - set format to colorbox
+    - select your desired node image style (example: thumbnail)
+    - set the colorbox image style (example: large)
+    - Exclude from display
+    - Configure the amount of displaying images in the "Group Multiple
+      Values" (Example: Show 1 starting from 0)
+
+  * Image field which is used to complement the colorbox images
+    - set format to colorbox
+    - select Hide (do not display image)
+    - set the colorbox image style (example: large)
+    - Exclude from display
+    - Configure the amount of displaying images in the "Group Multiple
+      Values" (Example: Show ALL starting from 1)
+
+  * Colorbox Trigger field which will connect the two fields and display it
+    - set Trigger-field to the first image field (the trigger)
+    - enter the field token of the second image field into the "popup" field
+      (example: [field_images_1])
