I have 2 forms, frmMain and frmPictures. In frmMain I have a timer whose interval is 5000 (5 seconds). frmPictures has 16 pictureboxes with images already loaded in them. In each timer tick I need to change the frmMain background image.. on startup the background image is the same as picturebox1.
On each timer tick, the program should randomly select a PictureBox in frmPictures and change the background image of frmMain to the image of the selected PictureBox.
How do I do this in VB.NET?

the images at application startup:
Then in the timer event, create a random number and pick an image:
