WordPress.org

Does the plugin support any options?

Yup. You can find them listed in the Installation section above.

Can't you just use an embed code directly? It's almost as easy!

Sure can, but lots of folks forget to swith to HTML mode first or the WYSIWYG editor messes up the code after the fact, etc. Postcasa allows for adding the shortcode directly to the WYSIWYG editor with no problems. Its a simple plugin designed for easy access, nothing more.

Does the plugin allow CSS styling for the slideshow?

Yes, to a degree. The [postcasa] tag options govern the actual flash slideshow, but you can style the surrounding HTML paragraph tags by using the included 'postcasa' class.

Example:

p.postcasa {
margin: 10px;
padding: 10px;
border: 1px #000000 solid;
}
