cURL FTP example please

I purchased the cURL extension and cannot figure out how to use it based on the example included. I want to upload image files to my server but the example is not clear about what to change and what not to change in order to get the extension working. Do I have to code my own php? I am not a php programmer. I tried to follow the example fusion file and entered my server, database name, user name, password into the php file but I do not know what else needs to change in the example php file. Also, the example fusion file doesn't make sense to me as I cannot determine if it is a complete working example. If anyone has a cURL upload example that will clearly show me where to add my own info and what to add, it would be great. Thanks!
