I like to put the images in most of my blog post because I believe that with photo, it can make the post look more interesting so that can help to reader to increase the ability to understand the content better.
But one of the worst thing is that the search engine spider can’t see the image, they only understand the word. So in order to let the search engine spider to see our images is only via the images tag attributes such as the ALT and Title.
SEO Friendly Images can help you to optimize your images and automatically updates all images with proper ALT and TITLE attributes. If your images do not have ALT and TITLE already set, SEO Friendly Images will add them according the options you set. Additionally this makes the post W3C/xHTML valid as well.
