ImageList promises me Alphablending, but how to enable it?

Question

I want my buttons to have images with an alphabet on them.
As indicated, I have included the TXPManifest component in my main form.
Below are some images uploaded to my project.

However, my BitBtn , which is linked to imagelist with an ActionList, is still disabled.

<- It looks like this at runtime, Yikes!

How do I get Delphi 2007 to work on my Windows 7 laptop to actually use the alpha channel , ImageList continues to tease me?

In response to @RRUZ, here are the properties of imagelist:

(Note the lack of the colordepth property)

EDIT
Alpha Blending works with TMS AdvGlowButton :
Therefore, perhaps this is not a problem with ImageList, as it is a BitBtn problem.

UPDATE 2
Downloaded and installed PngComponents . Entering TPNGImageList in an empty form instantly crashes D2007. (There might be something in the settings / paths / etc., But I'm too far from the original problem, so I throw the pursuit png).
So this will not work.

Answer 1

I suggest you contact Anders Melander Blog .

Hes has posted 2 relevant alpha blending posts in Delphi 2007:

• Alpha Blended Splash Screen in Delphi - Part 2

Very instructive.
