Have you ever wondered why some artists' work shows up so often in papers, magazines and online? I would wager a bet that the artists appearing most often in the media have very good images of their artwork ready well in advance of deadlines. This is, quite often, a case where you mother was right-- showing up is the most important thing.
For instance, when we are preparing to publish our magazine, Art Focus Oklahoma, the editor Kelsey Karper is frequently begging galleries and artists to send in print-quality images. A lot of times the same people have images prepared and ready to send. So, up your chances of getting good PR, have great images ready for any upcoming events.
