 ## Browser Support
 **respimage** supports a broad range of browsers and devices. It is actively tested in the following browsers and devices IE8+, Firefox (ESR and current), Safari 7.0+, Chrome, Opera, Android 4.1+ and IOS 7+, but should work in a lot more browsers/devices. IE6 and IE7 are only supported with the [oldIE plugin](plugins/oldie).
