I can use PhotoShop to create images and text over a transparent background and convert to .JPG files with no problems. But when I convert them to .BMP files I always got a default white background. Does anybody know how to circumvent this problem? I badly need .BMP files with transparent background.

BMP files do not support transparency. If you want transparency use PNG or GIF or leave it as Photoshop.

Also, depending on your program, the way it works, and how you intend to use the pics, you might be able to specift a transperent color in the program itself which will cause the program not to draw anything at the pixel locations definded by your chosen transparent color.  

This strongly depends on the program you are using the .bmp's with.
Otherwise, you should try and use the file formats mentioned by above weed.

I need to use .bmp file in Visual Studio C++. The dialog-based application only takes .bmp files when I design a Dialog. If someone can tell me how to get around this that will be great.
