Please find the attached image. If you look at it on the right hand side on the top of the dialog, you can see an image .
I have used the following to have it done
!define MUI_HEADERIMAGE_BITMAP "Banner.bmp"
!define MUI_HEADERIMAGE_UNBITMAP "Banner.bmp"
But, I'm not able to stretch that image across the text area. It wither appears on the left or on the right. I want to strecth completely on the top of the dialog as shown byt the red line
I have the Ebanner plugin. But not able to do it using the same .
