Banana !! I'm mainly posting because I'm intrigued as to what your project entails. "Convert picture files to font files" is not a simple project at all, especially if you want output of any quality. Fonts need to be vector, a PNG file (no matter how high resolution) is only raster. Are the 97 files glyphs to make up a typeface? If you have them in SVG or Illustrator/CorelDRAW format then it's a lot easier but still quite hefty. Maybe you think I'm being a douche here but I'm not (intentionally). Maybe you could send me a sample of your set of files so I can understand - heck, once I see it, maybe I can do the work for you. Basically, I guess, I'm super super curious :)
