dtgreene: Many users actually wound not want these features.
Pictures: These use up extra bandwidth (making the page load more slowly) and increase the amount of scrolling required.
Oh my God! You have to move your finger one time extra to reach the end of the page? How awful!
dtgreene: Also, some pictures are rather disgusting or obscene, which leads to another way to harass other users or make the experience of using the forum worse for everyone.
That's a moderation problem, not a "pictures" problem.
dtgreene: gifs: Now we add animation to the mix. Many users (including myself) just want to read the text without being distracted by animations on the screen.
Distracted? Really? Are jingling keys and shiny objects a problem as well?
dtgreene: Even worse, some animations (particularly those with lots of flashing) can cause epileptic seizures in some people, providing another way for users to attack other users. (Case in point: One episode of the Pokémon animé, Electric Soldier Porygon, made the news for causing seizures in children. The episode was pulled from the air (and never aired overseas), but you should be able to find the fair use clip of the seizure inducing portion (which I will *not* link here for obvious reasons).)
Less than 1% of the world population has epilepsy, and only around 3% of the people who have epilepsy get triggered by flashing lights, and even then it's only specific types of flashing lights, and that's assuming that anyone would even bother to post something that qualifies in the first place. There's probably less than 100 people in here. This is not a problem in this forum.
Also, really? You think people will use gifs as a weapon now?
dtgreene: Videos: Now we add audio. Having audio play automatically is one of the worst features a web site could ever have. Plus, audio can cause hearing damage (screamers, for example) or trigger audio related conditions like misophonia. There's also the issues of server space and bandwidth.
Cool. I never said they should play automatically. Of course they shouldn't play automatically. I didn't even think that had to be specified. Also, do you wear earmuffs when you go outside to protect from the threat of loud noises?
dtgreene: So no, I don't think these would be good features to add. Images can be posted as attachments, and if somebody wants to post a video, she can upload it to a video hosting site and link to it here.
That nobody uses as it is, and nobody clicks on them anyway, because it's impossible to know what sort of image will be attached, or video or website will be linked, so they don't trust enough, or bother enough, to click. Of course the videos would be posted to Youtube regardless, I just want to be able to be embedded. Like either the Barefoot Essentials or Adalia Fundamentals script has done in their endless struggle to make this forum not quite as terrible.
How about this? Me and everyone else who feels like it can start threads sharing funny pictures, or gameplay videos, or gifs of cute animals, or wallpapers, and we'll all enjoy ourselves; and you can just not take part of those threads? And just endure the, what? Maybe 5 pictures or gifs you'd run into for the whole month in random threads? Instead of saying the frankly negligible impact it would have on your forum experience would trump our enjoyment?
