I have not tested them, but I have a few ideas that you should check:
1) How are files placed on the iPad's โlocal driveโ? you donโt have HTTP, so I assume you have an image on your hard disk (RAM) - try opening the file directly in the browser, does it show / load?
2) Try adding: "display: block;" to your CSS rendering. Could do the trick
3) IMG tag, try adding width and height, will something change?
4) What type of PNG file are you using? 8-bit or 24-bit?
5) What happens if you use GIF or JPG?
6) when using background images. Try using a long format for the attributes .. "Background image: URL (image.jpg);"
7) Also try adding <!DOCTYPE html> so that the browser goes into HTML5 mode.
