What is most SEO optimized image HTML code for

Question

i got to know that  images can have title attribute too

<a href="http://domain.com" title="Keyword"><img src="image.png" alt="Keyword" title="Keyword"/></a>\

is there any other optimization i can do 

Answer 1

its better  that each image has an alt attribute and dont over optimize the links the alt tag must imply the information in the context

a popup created by the title tag  comes up if you put the pointer on the image  for 2 seconds this is used to describe the image and will be an apt position to put  the keywords in
