Can't switch to Pencil tool in Photoshop CC 2018
I have selected the Pencil tool but the only options I can get are for the Brush tool. I'e looked at the Help and there was an answer in Feb 2017 but that doesn't seem to apply to 2018.The options window looks completely different. I have tried clicking on all icons that look like a brush tool hoping to get it to change to a pencil tool but no luck. The only options are for soft round brushes. I would add screen captures. I've tried png, gif, and jpg and get "That image type is not allowed." what image type is allowed?
