The
first and most important rule to remember is that we can ALWAYS
shrink your image as much as we need to. We cannot, however,
BLOW UP your image
without losing resolution and image quality. That being said,
you should usually try to give us the biggest picture you can.
Don't worry about the file size. Any file extension will do.
(.jpg, .gif, .tif, .psd, etc.)
For
you artists out there, please send us your artwork
in vector format if available. Please make sure all text is
converted to outlines, and send file in .AI or .PDF
format.
