Bitmap in Button causes Error
So, I read about this problem a few times. I imported an Image and converted it into a button. Then this Error appears: "Content with both Bitmaps and Buttons may generate local security errors in some browsers if run from the local file system."
In Firefox everything works, but in Chrome and Safari it doesn't. I read that this can be fixed by using a local web server. The problem is that I can't do this because it is a project for university and I'm supposed so just hand in a html file.
But what can I do? I tried to put a button over my Image, made it invisible and used it for my functions. But i need something that I can convert to a button. I tried text or a shape but the same error appears.
