There are two things you could do (first way will not speed up the processing but is just a method improvement):

1) Only need to check the alpha channel (assuming any transparent colour is counted)...
If objColor.A != 255 Then ...
(As the alpha channel IS the 'trasparency' aspect of the colour, you only need to check this).

2) Lock the Bitmap and loop through the raw data (this is REALLY fast)... loads of examples on web... from msdn[^]

Also... if all you want to know is if the image could contain transparency... check the PixelFormat of the bitmap for transparency.

Hope this helps.
