Easy prevention of unintended lines after crop in Photoshop cs6?
After cropping and saving for web as jpeg (maximum, optimized, convert to sRGB selected) there are unintended 1px gray lines around the border of my images that have a white background. I've read that I can flatten to remove these, but do I flatten first then crop, or crop and then flatten? I imagine it's the former. Are there other ways to prevent these lines?
