Add text to png file.

I have 5 png image files, each is a different color of a simple balloon map marker.  I'd like be able to dynamically insert/edit/add a number to each.    The numbers could be from 1 to 250.  So, with 5 colors, I would need 1250 png file to cover all combinations of colors/numbers.  I'd like to use the 5 colored png files, and then dynamically insert a number, centered within the ballon.

I'm using the Google maps javascript v3 API, and map marker.   Unless maybe there is a way using the API to add numbers to a png file that is used as a map marker?

I converted this to vb.Net on the fly from:
http://tech.pro/tutorial/654/csharp-snippet-tutorial-how-to-draw-text-on-an-image

Adjusting for a dynamic width / height of the images.

Dim strFormat  as StringFormat = new StringFormat();
strFormat.Alignment = StringAlignment.Center
strFormat.LineAlignment = StringAlignment.Center

Dim myBmp as Bitmap = new Bitmap("C:\\myImage.png")
Dim g as Graphics = Graphics.FromImage(myBmp)
Dim i as Integer = GetRandomNumber() 'implement to return 1 to 250.
g.DrawString("My\nText", new Font("Tahoma", 20), Brushes.White, new RectangleF(0, 0, g.Width, g.Height), strFormat)  'it may be myBmp.Width, myBmp.Height
