Hi, I want to know how to how to optimize image for a particular website. Kindly please help me some one.
By optimize, do you mean optimize it so that it's more likely to appear in Google Image Search? If so, you can change the filename to be keyword rich: blue-widgets.jpg, rather than 399059055.jpg. And then also optimise the ALT and TITLE tag you use when showing the image - so "Photo of Blue Widgets". And then make sure it's on a page that's full of content relevant to that keyword (relevant page title, H1, content etc).
Good advice mate. I'd add: Include image reference in sitemap ( checkout Google's official blog from April 2010 for details ) Put the image above fold and of larger size ( Google seems to prefer those, esp Google news )
Google has a REALLY cool tool called Site Speed http://code.google.com/speed/ Its a firefox plugin, and amongst other suggestions it tells you which files should be what format and how much bw it will save.
add alt="you keyword" to any picture that you want to optimaized. google will read alt instead of picture.
If you mean image optimization to get high rank in search result then you may use your keywords as alt tag. Thanks
