Image Replacement Using Cufon (Javascript), SEO effects

[zco_seo]

Hello Friends,

I am using Cufon for image replacement in my website. May I know, does Cufon have any negative seo effects?

Will this affect the search engine ranking or loading time of my website?

What are the advantages and disadvantages of using cufon in a website in seo perspective?

Matt Cutts posted a video about something similar a while ago answering the question how to handle replacing fonts with 'images'. His answer could be found here.
