I enjoy a story with pictures in it, but no amount of pictures can compensate for terrible writing. I absolutely hate when a story uses too many pictures; it becomes very overwhelming at that point and it makes it difficult for me to focus on the story itself. All things in moderation. As others have pointed out, a good story doesn't need pictures.
EDIT: I should also add that some pictures look stupid as all hell and it makes me hate the story even more for making me look at it. For example: JJJ-thebanisher's story "Mattias the One Knight" has several pictures of little boys. Understandable, the story's main character is a little boy, but something about those pictures make me feel mad. First you have a kid dressed as a cowboy pointing a finger gun, then you have a kid smiling, then (and this one sends me over the top) you have a kid hugging a damn tree! Why is he hugging a tree?! Why? I couldn't even finish the story because that one picture gets to me so much and I don't know why.
