I would like to let users make a picture gallery in Drupal 7. I have the gallery formatter and colorbox modules loaded, but can't figure out how to use it to make a gallery content type that users can use to create their own galleries.
I followed this:

Installation:

  1. Extract Colorbox library in your sites/all/libraries/ folder
  2. Install Gallery Formatter and Colorbox Drupal 7 modules
  3. Create a new content type, or add a new field to an existing content type
    • Select 'Field' as 'Image'
    • Select 'Widget' as 'Image'
  4. Apply primary settings as required: Public or Private files, and a default image if necessary - click "Save field settings"
  5. Apply secondary settings as required: most of these can be left blank without consequence. Change the "Number of values" dropdown from '1' to 'unlimited' for good luck.
  6. Click on the "Manage Display" tab near the page top, and next to your new field change the 'Image' format to 'jQuery Gallery'
  7. Click on the right-side gear to change Gallery Formatter settings - select 'Colorbox' from the 'User jQuery modal for full image link' box near the bottom - click 'Update'
  8. Save the content type, and make some galleries.
But it is the last step that does not work for me.  When I try to make a gallery page, and upload an image, I get:
What am I doing wrong?

Thanks,
