If you take a look at the thumbnails of the pictures that I placed on my page a lot of them have the head cut off I wanted to know how to make it so this doesn't happen.

Guessing that all of your images are set to adjust to a constant width to fit into a box. Therefore any portrait images have to be clipped vertically. Either photoshop all of your images so they are square to begin with, or change the width=xxx to height=xxx and it will force the height to fit, but result in a narrower image than the box width.

It looks like you are using a gallery plugin to manage the photos. You have 3X5 photos that you are trying to put in a square frame, something has to get cropped, so oit is cropping from the top and bottom to get the square.

Check the plugin and see if you can make your own thumbnails. I know that in NextGen there is that ability

I'm using the program that comes with wordpress under. I changed the size in the settings part on the dashboard but this helped only a little.
Does anyone know of any good plugins that would help woth this?

try the ' NextGen Gallery' plugin

Thank you for the plug in advice it works great.
