I've had photoshop for ages but only really use if for photo editing, not for anything fancy, and I'm aware of how much work goes into the amazing graphic effects some professionals can achieve with it.
That said, i believe you can buy packages of 'effects' to download, and I was wondering if I could buy one that does the colourful 'paint splatter' type effect to apply to a black-and-white head shot of my daughter to make an arty-type print for my wall. My questions are 1) Would this be a waste of money, as I would need weeks of training to make it work well, and 2) If i could do it, where do you download photoshop 'effects' from that is reputable and not going to bring viruses with them?
