Added tidbits

Hey Erik, 
I've been tinkering around with your plugin (nice job) for a project and happened to run into the pagination bug I've seen reported in a couple places. For us it was a problem with having the WordPress search results not match the Google search results (we were searching 3-4 sites). 

So I fixed that. I also added in the ability to pass through images returned from the google search to use in the search template. 

Keep or discard the changes to the readme's, but I'd appreciate a link back to either http://profiles.wordpress.org/mikengarrett or http://webdevelopmentgroup.com. 

Let me know if these will work. 

Thank you!
