Hi, I'm finishing doing an upgrade to an application I developed near a decade. So they asked me to change the icon set (.bmp files) for all my buttons and menus so the users recognize the changes visually also. I was searching on the Internet for icon sets but I find them mostly in .png format, I tried some of them but when I use them in my application, the transparent regions of the pictures turn into black or white in some cases, so I would have to edit them and save them in .bmp format and adding a .msk file for white regions. I have a lot of icons (.bmp) but I don't want to waste my time editing the .png icons. Is there a way to use .png pictures in my application without having to edit and changing all of them into .bmp files?

TIA
