When I create a campaign, I generally create a whole new world. The problem with this is that even though I have a plethora of amazing ideas, I just can't handle all the drawing and visuals that I like to show my players while they play.
I usually just use Google to search for some images of monsters, castles, forest, etc. I then put these images on my iPad and display them when they are relevant. Do you have any resources or tips for finding images like this? Preferably images which all follow the same "style".
