Theme fails the dotmobi tests

Hi

I have installed the mobi theme and I have run the compliance test at http://ready.mobi/launch.jsp?locale=en_EN

The site fails the test in several issues, as follows:

• XHTML Mobile Profile: http://pc.dev.mobi/?q=node/200
• Valid Markup: http://pc.dev.mobi/?q=node/198
• Popup windows (created by img-assist module)
• Specify image sizes: Specify the width and height of images in pixels as attributes of the IMG element. This allows devices to leave space for the images when they arrive, which means that pages don't have to be re-drawn several times
• Page size limit: Page sizes (including images and stylesheets) should be kept small since large pages take longer to load and increase data charges
  FAIL near line 174 column 8
  The size of page markup is 25800 bytes
  FAIL near line 174 column 8
  The total download size for this page is 65582 bytes
• Structure: It is good practice for all but the simplest documents to indicate their structure through headings and sub-headings. Using structural markup, rather than formatting effects, allows easier adaptation of content where it needs to be divided into several pages, as well as potentially facilitating access to the sections of the document that a user is interested in. Where headings are used they should be used in accordance with the specification, i.e. they should be properly nested according to their level

I hope this helps to fix the theme. I'm willing to test any new version.

Kind regards
