Hi Douglas, you just need to create two global variables. Load the bitmaps to these and that's it. You don't need to load bitmap again, just call the global variables instead.

Take a look a look at the example: AnimPlusDemo_Drawables - AnimationPlus (informatix, as usual )
it is very nice.

B4X:

Dim Mygoback As Int : Mygoback = 1 ' =  toggle
Dim btnchange As Button
-----------------------------------------------------------------

Sub btnchange_Click
        Select Mygoback
              Case 1
btnchange.SetBackgroundImage(LoadBitmap(File.DirAssets, "go.png"))
              Case 2
btnchange.SetBackgroundImage(LoadBitmap(File.DirAssets, "back.png"))
              End Select
              Mygoback = Mygoback + 1
              If Mygoback > 2 Then
              Mygoback = 1
              End If
End Sub

load both images in activity create, then alternate their (visible) property of the two images. button image are very tiny so they will not consume much memory resources.
