You would open the stock image and edit it. That's what most people have done. But, if you are good with graphics, you could create your own. You just have to make sure that it has the SAME filename as the original image.I download the stock SpringBoard.app from MMi, but those PNGs in that folder can't be opened by photoshop.
Say I want to mod the battery charging image, do I start from the scratch or do I open the stock one and make changes to it? For others changed their battery to any other color, did they just mod the stock image or made a totally new one with similar graphical effects?
To change your battery color, you only need to change BatteryBG_5 through BatteryBG_17 and BatteryFill.what's the purpose of BatteryBackground.png, BatteryFill.png and BatteryReflectionMask.png?
I know there are ready to use battery images in different color, but I want to know if I only change the battery to blue, do I change BatteryBG1-17 only, or do i need to change BatteryFill.png and BatteryReflectionMask.png as well?
