WP Fluid Images runs when you insert an image into a Post or Page. It removes the fixed width and height attributes from the image tag. If you insert an image from the image uploader, by default, a width and height attribute is inserted into the image tag with fixed pixel values. This plugin prevents this from happening, because this can be problematic if your theme is built using responsive design methods. The plugin also adds a style tag near the end of the document that sets a max-width rule of 100%. This helps ensure that any image in a Post or Page won’t extend past the width of the Post or Page.
If you resize an image in the Visual Editor, a new width and height attribute get added to the image. WP Fluid Images loads a jQuery script that examines the closest parent div for image tag…

Replaced the max-width value with 100%. Updated the Readme to include basic instructions on overriding the default img width value. Calculated percentages accurately for images that are part of a WordPress gallery. Updated the jQuery javascript to start at the .hentry element, rather than a div to take into account HTML5 elements.
