How can I convert?yep, it always saves in .bmp, but its easy to convert
You can easily use PalApply to convert bmp's to png's quickly, but you need to open your images (specifically not indexed) in layers with GIMP or Photoshop for extracting all the colors from every single layer of images (open). It's just to make sure that the images have the same colors as/for a palette. I always use images as layers to index and save one as png format (sometimes gif) as a palette. You don't have to save all the images for a palette. One is enough unless you miss one image that has an extra color or more. Double-check if you're unsure. The point being is that what you want is for those images to have the same color palette as your target image. That way, when you convert the images with your new palette, it becomes faster to save in png format than just manually saving them one by one.How can I convert?
