Use Images! Use Keywords on images!
Have my site running for some time, and was really surprised to see it on 4th page.
But was even more surprised to see my images for particular keyword on the second line.
Is you do search "dog swallowed a sock" and check images you will see 3 of them there pointing to http://solved4u.net/maksim-volkov/my-dog-swallowed-a-sock.
Make sure you select those images to open Article they are attached to.
People are visual, and do search by images so it is extremely important to have Nice images pointing to your blogs.
