Appologies if this is the wrong forum but this is a little bit of a few things....so i dont quite know where it should go. I have a site that is performing well in the serps but has high res images in a image rotator on 90% of the pages. This affects the speed onload a little (allot). the image rotator is javascript based and basically uploads all the high res images and then shuffles through them by having a fade transition and changing z-index. i cannot compromise the image sizes as it affects the hi res end result.....so all functions well except in slower countries it struggles a little with the image uploads.
I would like to change the rotator to an swf/xml rotator where the images are still rotated and transitioned but the images are requested by the xml file when needed so the page loads quicker as at the most it only needs one of the hi res images at a time....so this solves the speed issue but i do not want the seo compromised at all..and this is my main concern. the hi res images have alt="" so no alt-names.
will a switch like this on roughly 700 pages affect anything with a site that is already performing well but needs a little turbo boost. I have looked into this especially since gorge announced the site speed issue and i have noticed that some of my competitors for this site load a little quicker.....hope this all makes sense and i would appreciate any advice or input on the "seo" being compromised or not..thanks
