This is a sandbox project, which contains experimental code for developer use only.
This module allows you to use Image field caption (link here) with a new feature; you can click into images to increase zoom. Especially useful when images have text inside and screen is not too wide (for smartphones for example).
The library used to this feature is jquery-peakzoom (link here). This can change in the future.
Now this affects to all images, enabled/disabled chance into field formatter configuration will be implemented in future.
