How does google index images

I have included alt text in all my images of my website. but still non of those images is indexes. what should i do next

 

make sure the names of the files are descriptive. surround the pictures with text describing what the image is about.

 

Log in to Google webmaster tools, and opt into "Enhanced Image Search"

 

I have some crystal crafts pictures, if I can put them in google search?
Is there any article about images search seo?

 

I have put description on all images. plus the pictures apear in rich content pages. but still cant see results

 

I have done enhanced image search too. does it have any impact on indexing

 

Wrapping keywords around images works great !

<td>keyword<br><p><img src=”image/keyword.jpg” alt=”keyword”>keyword</p></td>

Code (markup):

 

Is that allowed? It looks rather spammy to me and open to abuse.

 

SEO for Google images

 

The HTML in the link should look like this, it needs to contain the image size, title and alt tags.

<img height="100" width="100" align="left" title="Descriptive Title" src='http://exampleURL.com/' alt='description for Google' />

I wrote a post on it:
