updating resize image function

Retina of the same size

Fixed a bug, Retina image of the same size as origin bug was shown incorrectly.

Fix always resize for retina sizes

• Bug fix of a performance issue with retina sizes: #30
• Contributed patch to allow specify default tag of rwd_attachment_image() with a filter hook.

Fix background usage if no other options specified

Fixed a bug:
In case you use only background and all other options are missing (for picture and img) - background responsive image don't work.

Dev mode on existing sites fix

On existing sites there are valid database with sizes. However, if files are missing (for example you setup a copy, but didn't download uploads), then old version doesn't work and show nothing.

This is fixed and now it will show a placeholder if you delete a file from disk after it was resized.

Dev mode placeholder image improvement

Small improvement to placeholder images: now they print attachment ID and not only size.
This update was added to debug different image sources on different screens.

Dev mode with placeholder images

In DEV mode plugin does not resize any images and simply use placeholder images. This can be used to reduce disk space, while you develop and configure our plugin to match all required screen sizes.

To enable it you need to define new constant in your wp-config.php file:

define( 'JRI_DUMMY_IMAGE', true );

Editor content responsive images

After some WP update responsive images inside main editor's content stop working. Now editor use rwd functions to print content images as well.

Compatibility with JIO v1.1+

Added compatibility with Just Image Optimizer v 1.1.+ (Google page speed optimization for images)
