Ok, I cannot be sure which formats the nav accepts. Maybe also gif87.
I just know that I got an error when I had 72dpi. But there could have been sth else wrong.
I took a fresh navboot, inserted the 96dpi images and the text and it worked.
I use Photoshop with a gif plugin.
The text is restricted to 24 character by my program. But I could only display 23.
Let's see if some people offer that on ebay. And let's what happens when they screw their customer's nav.
I wouldn't do that and I don't intend to. I just provide the software with some advertising
Maybe I can sell the advertising space
