A digital file works best for photos and to capture prints without the mess of ink.  Use good lighting so you can get a sharply focused photo without blur from the camera - shake.  For best resolution fill the entire frame with complete nose or paw print.  Use the 
"upload" feature on the website or email high - resolution JPG file to Lorraine@keepsakesforus.com and include order number in subject line.  Or place order, then reply to order confirmation email and attach files.
