    You can try Picture.Compare (https://support.smartbear.com/viewarticle/72669/) as suggested by somebody else also.

     

    Cosider the following VB Script taken from the above link: 
     

      Set imageOnDisk = Utils.Picture 'to obtain empty picture object
      Set actualPicOnScreen = (Aliases.page.obj).Picture    'capture yourMappedObj's image
     

     imageOnDisk.LoadFromFile("D:\Data\img1.png")
      
      ' Comparing the images using the Compare method
      If Not imageOnDisk.Compare(actualPicOnScreen ) Then
        Log.Picture imageOnDisk, "Expected Image"
        Log.Picture actualPicOnScreen, "Actual Image"
        Log.Error "The compared images are not identical"
      End If

chik's question is a good one. Comparing images as part of an automated test, while useful in a limited fashion, is something that should be evaluated. If you are checking if a label has the correct text or if the color of a button is correct or such things, it's probably better to do object comparisons.  Check out the support article here for how to use that function.
