wait a minute. I forgot to say that I don't even need the transparency 
feature of the Image class. I only use Image - as I said - because of 
Image[x, y] pixel access. For the meantime - or as a final solution? 
there may be a lot of those accesses and I thought using Image[x, y] 
will be the most efficient way to go - I switch to using an 8*8px 
Picture and Draw.Pixel() instead but I would really appreciate anyone 
clarify this topic to me.
