Photo optimization of image optimization for search engines should never be an afterthought for your website. There are small tweaks you can incorporate into your blogging practices that, while they may not send your site zooming up the search engine listings, will nudge your site upward over time. Even if image optimization doesn’t give dramatic results, the effects add up, and in any case, these practices will definitely not harm your search engine rankings.
Always include a keyword in your image name. Images with names like DSCN4321.jpg provide no information to image search bots. But if you name it something like “mens-blue-cashmere-socks.jpg” it will provide lots of information. Beware that if you use spaces in your filenames, they will be encoded, so if you name a file “cashmere socks.jpg” it will be encoded as “cashmere%socks.jpg.” Use hyphens instead of spaces.
Use “alt” attributes to provide extra information if for some reason your image doesn’t show up on a browser. You can see an example in the first screen shot. The second screen shot shows how using alt attributes can give the reader information if for whatever reason the actual image doesn’t show up or isn’t supported in their browser configuration.

Optimizing Images For SEO
Surround your image with descriptive text so that the crawlers can make an informed guess about what the image is in case filenames, and alt tags and title attributes aren’t available. This is more of a “belt and suspenders” approach, but it certainly can’t hurt and could help your SERP rankings.
