Opportunity is missed by most people because it is dressed in overalls and looks like work. - Thomas Edison
If your customer is sending you images that small, chances are, they're getting them off the internet. Chances are, they're not paying for them and feel entitled to them since they "found" them somewhere. They don't want to pay, so they steal.People hating to pay for art isn't an excuse. I hate paying for everything. As someone who makes his living from making art, hearing a line like that chaps my hide. No budget for it? Then just print it exactly as they give it to you and see how they like it. Stop giving away your time to keep a customer that doesn't value your time.
