Hey, just wanted to say thanks for this quick and easy tool and for the prompt to learn some .bat file making too! I was using another tool to make the splash screens for my EVO lte, but the site has stopped working for some reason and the dev hasn't responded or fixed it. So on to google search it was. That led me here and now viola, I have my splash screen.
Just to put this out there, you can use this tool for other devices, you just have to know what size image your device needs. I put my 720x1280 jpg (evo lte size) in the folder and it worked perfectly.
