So, I'm developing a forum and I'd like to allow people to attach images to their posts (1 image per post) if they want. Now, I could do this the way Facebook does, that is, if there is a URL in the post, parse it and if it's an image, show it. Or I could just allow image uploading.
Of course, the first option is easier to develop, cheaper and probably more secure. But from a user standpoint, would it be too much hassle for the average user to upload an image to a service like ImageShack and then post the link?
