Frame Changes size(DX7/VB)

Say during an Animation the Size changes, I want to keep the frame in a general position so it doesnt "shake", How would I do this. Heres what I am working on, When it reaches certain frame the size screws up. And only if your going from a bigger frame to a smaller frame some of the bigger frame gets left behind, how do i fix this. Please Help. Attachment Zipped. again plz help. thx

okay, I'll try to make the concept less confusing so you don't have to dl the example. Say I have a 10 frames Animation of a Square growing. Since I use this

Dim r1 as RECT
r1.Bottom = rSprite.Top + 70
r1.Right = rSprite.Left + 53

WHen I blt The viewable area of the animation of the sprite wIll ONLY be that big. I want to get the dimensions oF the frame when it changes and make the viewable area = that of the frame. So the viewable area would change with every growing frame.

Since I use this type of frame lookup

VB Code:

Frame(0).Top = 0: Frame(0).Left = 52
    Frame(1).Top = 0: Frame(1).Left = 103
    Frame(2).Top = 0: Frame(2).Left = 154
'etC

It only specifies how far down and right of the bmp to look. I cant get the frame dimensions this way. I was thinking of using a color seperator for each frame(green square around it) I really need help with this, SINCE no tutorial I've read shows you animation where the frame size changes. PLEASE HELP, I appreciate the help. Thank You

sorry here the bmp, had to convert to jpg to post it. Again I really need help. Thx
