Hello,
"The html tags not allowed are that way by design
for security reasons. Where to add them is in the config.php
but you may open yourself to vulnerabilities.

Use the block creator HERE to help you create a block file to display your java.

You can use iframes. Use something like:

^^ you can create a module to display as one of the left links
or make a block. That site also has a module creator.

You wanted to install another gallery? Do you already have one, and
want a second? Which one do you have now?
