I have expanded the scripts to work on blogger to use its hosting only.

If any case gallery and read more hack not working you can upload these script to your server and keep them 
in blogger codes in the below format before </head> tag.

<script src='http://script-hosted-url/jquery-1.2.6-packed.js' type='text/javascript'/>
<script src='http://script-hosted-url/jquery.cycle.all.min.js' type='text/javascript'/>
<script src='http://script-hosted-url/readmore.js' type='text/javascript'/>
