You made an Facebook app for a Facebook page, but it doesn't seem to appear among the apps on that page. No biggie, let me show you how to connect a Facebook app with a Facebook fan page.
Some web pages have the Save image As... option disabled on a right click when you try to save an image. Let me show you how to get that image anyway using Firefox.
If you don't want others to use your photos and images without your permission, you can create a so called custom watermark with your name or any other text you want.
