Optimized filename management for SEO

[mattam]

Hi,

I'm currently undertaking a project to manage better my images and to rank for image searches. My site uses mod_pagespeed to optimises images, therefore image urls are changed to a pretty seo unfriendly url or even sometimes inlined within my page. On top of that I generally resize all my images by passing the desired file dimension within the image url in order to optimise the loading time of my site.

Is there a way to provide a hint to google that I have a much better quality image with higher dimensions and better name?

Can i specify within my image sitemap an image that actually does have different dimensions and a different within the page it serves?

Are there better tricks to achieve that?

Thanks in advance
