The problem with finding images for pornographic or even only semi-erotic works is how most of the image used to promote it are sexually suggestive and I tend to avoid them, but sometimes I never find something that isn't explicit or extremely suggestive and the safe-for-work images I do find are basically random scenes that seem to do little in showing what the work is about.
The "uploading and adding images to a page" page did not help me on that regard.
