How to Configure the WP Retina 2x Advanced Settings
In this guide to WP Retina 2x, we will show you how to configure the Advanced Settings, including picture replacement technique, image quality, and more.
Step 1) Login to the WordPress Dashboard.
Step 2) From the left-hand sidebar of the Dashboard, navigate to Settings -> Retina.
Step 3) Click on the Advanced tab.
Step 4) Complete the fields as shown below:
|A.||Method||Select the appropriate Method that works best in your situation.
|B.||Quality||Enter the Image Compression quality in the textbox.
The default value is 90.
|C.||Debug Mode||Place a checkmark in this checkbox if you want the client to always be served Retina images.
|D.||Custom CDN Domain (Pro)||If not empty, your site domain will be replaced with this CDN domain (PictureFill and HTML Rewrite only). This option is only available in the Pro version (paid plugin).|
|E.||Keep IMG SRC (Pro)||Place a checkmark in this checkbox so that PictureFill src tags are replaced by src-set tags and consequently search engines might not be able to find and reference those images. Keeping it will load images twice for retina devices on old browsers. This option is only available in the Pro version (paid plugin).|
|F.||Use Lazysizes (Pro)||Place a checkmark in this checkbox so that HTML will be rewritten to support the lazysizes and the script will be also loaded. The images will be loaded in a lazy way (when the visitor is getting close to them). This option is only available in the Pro version (paid plugin).|
|G.||No PictureFill Script||Place a checkmark in this checkbox so that the script for PictureFill will not be loaded. Only the browsers with src-set support (e.g. Chrome) will display images. You can also load the PictureFillscript manually.|
|H.||Hide ‘Retina’ column||Place a checkmark in this checkbox to hide the Retina Column from the Media Library.|
|I.||Hide Retina Dashboard||Place a checkmark in this checkbox to hide the Retina Dashboard menu and tools.|
|J.||Admin in Retina||Place a checkmark in this checkbox so that the WordPress Admin will also be Retina. Some plugins (like NextGen) do not like Retina enabled in the admin.|
|K.||Ignore Mobile||Place a checkmark in this checkbox to disallow the delivery of Retina images to mobiles devices. This option is not supported by PictureFill and may prevent it from working.|
Step 5) Click the Save Changes button to save any changes.
