Hi! I've implemented a thumbnail extension for windows xp explorer by implementing the IExtractImage interface. The super weird part is about windows passing the desired BPP on GetLocation(). In Explorer: When the left bar, with the Information box, is active: windows requires 32bpp. And shows my image stretched (as wide as possible, and then super heigh). When in normal thumbnail mode, windows requires 24bpp: but it won't show the thumbnail unless it's 1bpp or 32bpp! If I force feed it 32bpp the thumbnail is shown nicely (not stretched as in the Information box). Does anyone have any idea as of why? :confused: Thanx /JP
