Quoted from Coindropper:
If you go back to the first post, I originally saved them at printable size. It was requested that I post the original sizes instead.
Just to be clear... it was the resolution (dpi) that people had issues with initially, not the size. You can resize images and still maintain high resolution images. But I actually print these on 4x6 photo paper loaded into my printer, so the resizing is done automatically by my Mac when printing and still maintains high resolution. I prefer the way you are uploading them now, so keep up the good work.
The way I see it, this is a free service, so I’m thankful for anything I can get... and more than willing to do any final prep work required to get perfect fits on my pins. Thanks again!! More than willing to make a small donation for the effort should you change your mind.
