nsis image

Hello, can some one help me with adding image without background to my custom page(not MUI)?

I have problems to adding image that have no background. I am trying a lot of plugins, but it doesn't help. The problem is when i fill the image with background color it's looking so horrible, but it's adding to my page.

And one more question.

I am also using default page (page directory) that automatically adding my icon image to the left top corner without any problems. At start of my nsi script i set up Icon variable like:
Icon "image.ico"

Can i find source of default pages to do the same?

P.s. my "image.ico" doesn't have background and when default page add this image there is no problems occurred.

Thank you!

Icons are normally transparent, other images are not. The directory page uses a static control to display the icon. There should be similar code available when using a custom page.
