Deep End of pool but I can't swim

So my sister’s site got moved and it still doesn’t work. It’s all flash. I KNOW NOTHING ABOUT WEB. I am a computer guy and I know what a path is and if there is a place I can change a path and have the correct path to change it to I can do that but that is about the extent of what I know. Don’t even know where to go to look at the content that might need changed. Site was built by a web guy that is not responding to calls. Any advice? The site is and the multimedia link isn’t working and there are generally sub folders under the photos link which fill up with photos from her ftp. She can’t currently see anything she uploads or reuploads to her site. Your help could be a great Christmas present! Best.
