insert_image_dimensions on <link>-elements causing invalid document #629

GoogleCodeExporter opened this issue Apr 6, 2015 · 4 comments


Copy link

What steps will reproduce the problem?
1. Create a valid html document with <link rel="apple-touch-icon-precomposed" 
sizes="144x144" href="touchIcon.png"> in <head> section.
2. Turn on ModPagespeedEnableFilters insert_image_dimensions

What is the expected output? What do you see instead?
The touchIcon.png shouldn't be optimized by the insert_image_dimensions filter 
because width and height attribute not allowed on element link at this point, 
causing the w3c validator to flag the document as invalid markup:

<link rel="apple-touch-icon-precomposed" sizes="144x144" 
href="xtouchIcon.png,qv=1.6.pagespeed.ic.2ZMkfb7qzF.png" width="144" 

What version of the product are you using (please check X-Mod-Pagespeed

On what operating system?
CentOS 5.9

Which version of Apache?

This was an oversight when we generalized image rewriting to cover icon links.  
It should be easy to fix.

In the mean time, you can either switch off insert_image_dimensions (possibly 
doing so just for validation and re-enabling thereafter) and/or just live with 
the extra markup, which should be ignored by the browser.
