Description
I've tried to redraw bitmaps used by Shell Image Viewer component. It's not perfect, but at least it works properly for most of themes, unlike the "originals".
These icons are supposed to go here:
/reactos/dll/win32/shimgvw/res
Sadly, I couldn't test 32-bit bitmaps (with partial transparency), because ResHacker fails to import them properly. Tested under Windows XP. It would be a good idea to use PNG for semi-transparent icons in the future (because 32-bit Windows Bitmaps somehow are not supported by the most of common image manipulation software, even though Windows uses them internally for toolbars).
