Ok, first I can't see the image unless I log in to the forums, and I'm not wanting to sign up at amy more forums...
Second, is the image you are wanting to be a Boot Skin your image or was it made by someone else? Because no one is going to make a Boot Skin out of someone else's work without permission...Or at least out of common courtesy we try really hard not to do things like that...
And Third, did you go to the tutorial and follow the instructions? Becaue Boot Skin can be a pain, but are WAY simple to make....the problem most people have is getting the color depth just right...Skin Studio has a tool specifically for prepairing images for Boot Skin...The 2 images both have 16 colors (4 bit). Most image editing software has the option to decrease the color depth, but sometimes even then it doesn't work just right...
I would suggets trying the tutorial using your image editing software...I use PaintShopPro 8, and then if the image still won't show up try using the tool in Skin Studio...
You can find the tutorial under the "Help" button when Boot Skin is open...you've got to be conneted to the new I believe...
