I'm just winging it here, so take it for what it's worth.
Put all three images on your report and pile them on top of one another.
In an event property (I don't know which one: open, activate, format), use the following code:
'if "A" then show pic a and hide pics b and c
If Me![fieldname] = "A" Then Me![graphiccontrolA].visible = true
Me![graphiccontrolB].visible = false
Me![graphiccontrolC].visible = false
Else
'if "B" then show pic b and hide a and c
If Me![Fieldname] = "B" Then Me![graphiccontrolA].visible = false
Me![graphiccontrolB].visible = true
Me![graphiccontrolC].visible = false
'otherwise show pic c and hide a and b
Else Me![graphiccontrolA].visible = false
Me![graphiccontrolB].visible = false
Me![graphiccontrolC].visible = true
End If
End If
I'm still new at this, so there may be problems here. Give it a shot!
