Adding bitmaps to themed rPreview toolbar

[peterk]

Hi Antonio

I am trying to add different bitmaps to the themed rPreview toolbar
These bitmaps are contained in my normal RES file (not in Prev32.dll)
I cant get this to work
eg below even thing Bmp_Pdf exists in my resources, it wont display

* Code snippet*
::oImageList:AddMasked( TBitmap():Define( ""BMP_Pdf"",, ::oWnd ), nRGB( 192, 192, 192 ) )

Do image lists require special kinds of bmps?
Would appreciate any assistance

Thanks
Peter
