1. That block is actually an external block outside the photopost program or admin panel. It is located in your photopost directory in a file called inc_features.php and within the configuration details at the top of that file you will see how many photos to display and how many rows.
2. There is no function for this as it would be considered a bug to allow that since a sidebar is suppose to open in the header etc and the program be wrapped in a td. It is not a template edit but rather a php file edit. You would need to ftp to your servers photopost directory and edit index.php and find this code and move it above the include for the menubar template.
