I'm not sure what the preferred way of appending an image to this list's 
postings is.

I believe I've seen something like that on Linux but I've not dug into 
it yet. I suspect that the colour representation varies, possibly 
depending on the system properties as interpreted by the TImage object.

Another thing that I've seen is that there's a massive performance hit 
if you have more than one tlazintfimage instance, I was able to code 
round that.
