mod_pagespeed does this nifty image-resizing, but only if "width= and height= attributes on the tag or an inline style= attribute" are set. This gets a bit problematic if you have e.g. an image blog with hundreds of posts and one day in the future might want to change the stylesheet, resulting in a new width for images.
So, is there a way to get both mod_pagespeed image-resizing and be able to specify the image width in a stylesheet? The insert_image_dimensions flag to mod_pagespeed isn't really helpful, since I can't specify image height, resulting in oddly stretched images.
The blog is running Wordpress, so perhaps there's some Wordpress-specific solution.
