I have no idea why, but using Delphi 2009’s ribbon control, the small images in the quick access toolbar don’t show up.
I’ve got an image list with images set to 16×16 pixels and when I use them as the regular image list, it doesn’t work, just shows the menu caption. If I switch to use the large image list it works, but adds extra padding and looks bad.

Any idea what is going on? Which of the multitudinous options needs to be configured to get this thing to act as expected?
In Delphi 2010, and XE, the steps are:
set Form.DoubleBuffered true, and Form.GlassFrame.Enabled true.
Double click ActionManager. This opens On the Action manager properties dialog. Go to Toolbars tab and click or double-click “RibbonQuickAccessToolbar1” to get focus on that toolbar. This step is important, it seems difficult to get items added unless you do this.
On the Action manager properties dialog, go to Actions page, and drag an action like Copy/Paste that has an image visible in the actions list, to the selected area on the form.
It seems easier to add a second item with an image to the QAT, than to add the initial one.
Let me know if that works for you in 2009.
