    You really want them redrawn as some form of vector (i.e. in Illustrator not Photoshop), as then you can resize them as much as you want, and not lose any detail.

    Photoshop can do everything you want or might need to do with any photo. I am talking about the pro version I am using, not the free one they include in every scanner and many cameras. The free version is really just a joke.

    But the problem is, a photo is not what you really want for graphics.
    I know the last major version of PS that I used was CS2, and it did have some vector graphic functionality, but Illustrator was what was designed for working with vectors.

    I use Photoshop for bitmap editing and creation but Illustrator or Corel Draw are the correct tools for anything which may require resizing where degradation such as jagged edges must be avoided in enlarged versions.
    You think that's too expensive? You're not a Model Engineer are you? :D

    I don't know the Illustrator, so I won't argue against. I am using CS5 but sure, mostly for photography, not vector graphics.

    For 2D CNC paths, vinyl cutting paths and any other graphics you wish to be able to scale without degradation you need a Vector Graphic not a Bitmap Image. Vector Graphic packages are unsuitable for working with bitmap images of normal complexity because every block of every colour would require it's own vector outline and colour fill resulting in enormous files which tend to be totally unmanageable, even a small colour gradient would have a huge number of colour bands.

    Morning was bored so I converted the images to vectors, this morning in inkscape using standard settings took 5 mins for all 4. I saved the images at 300 dpi but I also included the .svg files which are resolution independent so you can generate any dpi.

    Now these would need some post processing but I spent literally 5 mins on them, they're simple bitmap traces. Load the image in inkscape, click on the image so it's highlighted! Then select from the drop down menu path -> Trace Bitmap.

    From there you can preview the effect.

    I like the last skull which was done by playing with the settings in Trace Bitmap, make sure you then save it as a .svg the printers should be able to process an SVG but if not you can export the picture to a PNG just make sure you have the right DPI when saving the image.

    You should get on inkscape and play, Youtube is full of tutorials for Inkscape including trace functions and it's open source (Free) so there's really not any excuse not to.

    Nice work Desertboy. I opened skull rcmax.svg and it really is very nice. Yes, some cleaning is still to be done but the OP should be able to do it without much effort. Never tried Incscape but will definitely have a look at it, at least for this sort of work.
