Here is what it looks like

this program simply asked the user to click flag and a random number will be generated from 0 to 11 which represents the countries. I have my flags located in a folder "Projects\Flags\flags\China.gif" for example. Then the picture will be displayed in the picture box. Then the user will have to click on the correct country radio button(group into a panel). If the user click the correct country, a message will be displayed.

1. My question here is, how can i assign the country flags to a variable in sequence from 0 to 11, so that i could call it upon random number generation?

2. How can i later display the country flag in the picture box (from the location of the flags picture)?

Note : This is just a sample picture, so the number of countries varies from what i ma doing.
