How to optimize an image and gain benefits?One of my friends asked me few days back followed by one more yesterday; that asked me to put this on my blog as it should be useful to all who are unaware of image optimization.
If your image is correctly optimized, it shall come up in the Google image search.
By optimizing, you need to help Google decide what your image is. Below are some tips for optimizing images:
1) Use proper file names for your images.
For example, if your image is of Rose, your file name should be Red_rose.jpg
If it is in a folder, it should be in a folder called flowers or roses, etc.
2) Use the proper alt tag on your images.
For example, for Red_rose.jpg, the alt tag can be alt tag="American Red Rose".
The alt attribute is what determines the text that shows up when you hover your mouse over an image. Also, if due to some technical flaws, the image is not downloaded, the text is seen as alternate that says to the visitor what the image is of.
3) Use captions or relative text near the image.
Google reads that!
4) Use the width and height attributes on images.
It is advisable to put the proper width and height attributes on images. This helps for fast downloading of images and in a way is part of Optimization.
5) Make sure that your File-name, Alt-tag, caption, etc. are keyword-rich.

One more additional tip is to submit your image into Flickr or Picasaweb with similar keyword-rich tags.
