=========================
Web Widget - Image WebCam
=========================
This module extends the functionality of the image widget and allows to take snapshots with WebCam.
Configuration
=============
By default, the module works with all `major browsers
<https://github.com/jhuckaby/webcamjs#browser-support>`_.
An important note for **Chrome 47+** users - this module only works with websites delivered over SSL / HTTPS.
Visit this for `more info
<https://github.com/jhuckaby/webcamjs#important-note-for-chrome-47>`_.
But, If you still want this module to work with websites without SSL / HTTPS.
Here is the steps to do it easily (Always run in Adobe Flash fallback mode, but it is not desirable).
Set the configuration parameter ``web_widget_image_webcam.flash_fallback_mode`` to ``1``
Its done! Now this module also work with websites without SSL / HTTPS.
Bug Tracker
===========
Bugs are tracked on `GitHub Issues
<https://github.com/OCA/web/issues>`_. In case of trouble, please
check there if your issue has already been reported. If you spotted it first,
help us smashing it by providing a detailed and welcomed feedback.
