Jesus I hate that god-awful song, and now think less of one of your patients. It's so freaking repetitive! Who really likes that song?
but in terms of imaging software...
Corel is good, high dollar software (if you're spending your money on the high dollar software). I recommend that you explore the
Gnu Image Manipulation Program (aka GIMP). While I wouldn't replace a $500 adobe program with this, it's a definite helpful boost, and a decent substitute if you don't have such a program. But it's best feature is that it's completely free and even expandable to a degree. This in conjunction with a corel program would be pretty good.
