I'm displaying my records in a blocktable. I would like to limit 10 records visible to the user at a time and the user can scroll down to see the rest. How can I achieve this? Thanks

I have an image where i need to zoom in and zoom out the image . How do i go about it . Not getting proper solutions until now . Banging head onto this . Have taken image tag where following is the code:
 

<apex:image id="theImage" value="https://s3.amazonaws.com/{!bucketToList}/{!obj.key}? AWSAccessKeyId=AKIAJGN4J4RSRNW26IEA&amp" width="100" height="100"> </apex:image>
​

Please help !
