Usage of BMPs and GIFs in MFC application

[Rohini]

Hi All,

In MFC desktop application, what file formats (images) would be better
for screens and buttons considering the performance as main factor.

For buttons and screen,

I can use BMP or ICON in the resource script
I can use the GIF or JPEG files, custom control to draw this (file
read, and draw the buffer).

Performance wise which is better option to use in MFC application?

Assume that,
One application has 100 BMPs in the resource script.
Another application has 100 GIFs, I need to load and use these files.

Which application will perform well with respect to the performance?

Need suggestion.

Thanks & Regards,
