I used this to generate random BrandingImages for placing on the side of my installer during the installation process.
You can use the value generated like so:
IntCmp $R2 2 0 0 +3 SetBrandingImage "$TEMP\ddayupdates\left_logo1.bmp" Goto set_bitmap_end IntCmp $R2 5 0 0 +3 SetBrandingImage "$TEMP\ddayupdates\left_logo2.bmp" Goto set_bitmap_end IntCmp $R2 7 0 0 +3 SetBrandingImage "$TEMP\ddayupdates\left_logo3.bmp" Goto set_bitmap_end SetBrandingImage "$TEMP\ddayupdates\left_logo4.bmp" set_bitmap_end:
