In this app we will make a simple image gallery application. This application we will be importing the pictures to the windows form application resources and use that to display the images to the picture box in the app. Each picture will have a small caption attached to them, so when you are on the picture there will be a little description of what that picture is. The caption will also change when the pictures do. You can make a small app such as this and get some experience of the inner working of visual studio and windows form. This is a great way to have a small refresher on how to work with windows form application and c# in visual studio.
