I love my Mac. But I have some troubles. Did I do any wrong? Thx

I can\'t see the properties of a picture (the right click function of IBM system laptop). So, I can\'t insert the pictures. Also, it always tells me that can\'t support the application, but I\'ll try when I tried to open/write an article. It seem like is not compatable with this website. Anyone can tell me why? How do I see the property of a picture?
