AutoRun Wizard FAQ
Q: Can I create transparent splash screens? (47,006 views)
Yes, AutoRun Wizard supports creating transparent splash screen introductions.
When you select the Transparency option AutoRun Wizard will pick ONE background color that is most common and make it transparent (see through). For this to work properly the areas of the BMP file you want to have transparent must be the same color.
If you choose to use Transparent images your splash screen format must be BMP. You cannot use the Animation option or Full Screen option when selecting the Transparent option.
