All too often I see absolutely gigantic images on various boards. This is a problem for users with slow/limited connections (especially when not in image view with zoom controls), but it can also be a problem when GBAtemp itself gets a bit slow. Also, storing unnecessarily large images must make this site more expensive to run long-term.

Perhaps much more importantly though, lack of any image processing means image metadata (e.g. EXIF) has to be scrubbed manually before upload. I realise this is a "PEBKAC" problem in essence, but in practice, who even considers that their photos may contain sensitive information like geolocation or camera/phone model in them? Many other online boards/sites do this at minimum, if not process further, so I bet a lot of people expect every place out there to do the same and unintentionally leave themselves exposed.

If anyone caught and inspected the latest image I sent before I scrubbed it, now you know I took it with an R800i. Not something I'd normally share, but the mistake is on me ;)


Edit: Curiously, the vast majority of unedited images I manually looked through had no metadata whatsoever. I thought for a moment there is some automated scrubbing going on, but then I found a few counter-examples. Indeed, it is not safe to send images here before scrubbing them.

I could've sworn geographical data was scrubbed on here. Let me test this with an image I tagged myself:

geo-tagged-image.jpg


EDIT: Huh, indeed. The location stayed even after redownloading.

Fixed! Image metadata is now stripped on upload and we're retroactively pruning metadata on existing uploads.

As for image sizing and compression, that's not something we're going to do for now as Xenforo only does that with WebP and we all know how we feel about WebP.
