Sure you have every right to like or dislike an image, though perhaps a comment along the lines of, "Not for me I'm afraid, seems to be a bit of photoshop -----" (filling in the blank with a word that has some meaning and offering a more constructive criticism). Buggery doesn't mean anything in this context.
