It's as simple as activating the tool, and choosing the options you want to customize it the way you want!

Activate On-Photo Captions, Meme Generator Tool

Go to your website Admin Panel > Configure Site > Social Networking > Photo Uploads configurations page.

On the Photo Uploads configurations page here you can allow users to add text to their photos, great use as a meme generator tool, or for adding captions to photos directly on the photos.

You can allow users to add up to 2 text positions, with different position options for each (i.e. Center, Top, Bottom, Left, Right, etc.), give text color and font size options, and margin options.  Provide a preview option for users too!

Click the "Save" button at the bottom of this configurations page to save your changes.  Now in your Photo Uploads page you give your website users/members the option to add text to their photos / create and upload their own memes!
