What do you mean by "a random image"? A random number is easy to understand, but what is a random image?

Grayscale, color what? In short we need more info... Any requrements? You can generate random numbers with the Random class, and you can set the individual bytes in a picture array. So what is the problem?

I think maybe he means random sequences of polygon shapes of varying sizes and colors. as in "Today's winning number is 7 and the winning picture is a red square with a yellow circle in the middle containing a black star"

Or it's an ad rotator, or...

Why don't you use the CAPTCHA with numeric format?

I think the random image may be a cherry, lemon, and the bar, and a large assortment of other fruits. Slot Machine

A random image with random pixels on it ? That's trivial, just write code that iterates over the pixels and sets a random colour. Is that really what you want ? Generating random numbers is also trivial. If you don't know how to do that, and don't know how to find out, you can't know how to use google, or own any C# books. This sounds to me like homework, you should talk to your teacher if you're this lost. No way are you writing a lottery app that will be used for real, if you don't know these things.
