ImageList promises me Alphablending, but how do I enable it?

Question

I want my buttons to have images with alphablending on them.
As instructed I've included a TXPManifest component on my mainform.
Below are some images I've loaded into my project.

However my BitBtn, which is linked to the imagelist via an ActionList still looks off.

<<-- It looks like this at runtime, Yikes!

How do I get Delphi 2007 running on my Windows 7 laptop to actually use the alpha channel the ImageList keeps teasing me with?

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

(Note the absence of a colordepth property)

EDIT
The alpha-blending does work with the TMS AdvGlowButton:
So it's probably not a ImageList issue, as much as it is an BitBtn issue.

UPDATE 2
Downloaded and installed PngComponents. Putting a TPNGImageList on a blank form instantly crashes D2007. (Maybe something in the settings/path/etc, but I'm drifting too far from the original issue so I'm dropping the png pursuit).
So that doesn't work.

Answer 1

I suggest you to refer to Anders Melander's Blog.

Hes has published 2 relevant posts both related to alpha blending under Delphi 2007:

• Alpha Blended Splash Screen in Delphi - Part 1
• Alpha Blended Splash Screen in Delphi - Part 2

Very instructives.
