VS 2008 - How To Make Animation Player Inside Class

I've been trying to make basically a simple animation player inside a class so that I can use it in a game I have to make for a school IPT project. When I first tested out some code I found, it was not in "class form", ie there were just loose variables as I was only animating a single .gif file. The code worked perfectly, and the animation was drawn frame by frame by the e.Graphics.DrawImage function.

Now that I have moved the code into a class (So I can run more than one animation at a time, though Im still trying to get only one to work), The e.Graphics.DrawImage function didnt work. It would draw the first image, but then (even though the function is called as shown by stepping through the lines of code), the picture doesn't update. I know the frame has changed as Ive kept track of the current frame in the debug window, but it still wont work.

I have had troubles like this with other GDI functions, where if the variable to draw is inside a class (etc) it simply wont work, it will only work if it is a loosely floating variable. (i.e. Sprite.Image doesnt work, If I just make an image it does). With the code below, I have tried in the e.Graphics.DrawImage function submitting me.wth.animatedImage and wth.animatedImage

Public Class Form1
Dim wth As New vsprite
Public Class vsprite
Public animatedImage As New Bitmap("C:Documents and SettingsSamDesktopexplosion.gif")
Public currentlyAnimating As Boolean = False
