If you want your own website rather than a hosted gallery, there are loads of templates you can use. I set mine up using a zenphoto template, and the process wasnt too hard to master. You will need a host for the site, then upload the template to that site and run the set-up files. It should then just be a case of setting your preferences and uploading images and text.
Mine is here -
