Most mature social networks do remove this information to prevent users accidentally sharing their locations. Can someone positively say whether Lemmy is aware enough to strip extra information from photos?
Exactly. Even if the standard Lemmy software does it, there's no guarantee that your instance admin hasn't altered the code or done something else to keep that data.
I’m hesitant to name anything specific since time exists and tech fluctuates, but there’s definitely a small, free utility app for your device that will strip exif data from your images.
Search for ‘remove exif’ in your App Store and see what people are saying about the top several apps listed.
(EtA: In nongeek, ‘exif’ data includes the photo’s gps coordinates, specific type of camera or device that created the image, timestamp, and other info, and its all quite easily viewable.).
Nerds use these apps more than most, so their reviews tend to go into some detail. There are certainly apps available that are easy to use on your device. Obviously don’t use an online service for this, either.
No no not needless. I haven't looked into it past what I've seen while lurking. I'm putting together a workstation for SD, but have only used cloud instances so far and haven't tried to use the embedded prompt. I merely noted it exists. Now I have something else to look up and reference. Thanks.
I'll have a look at this when I get a sec. I know the images are re-processed on upload (and cropped etc) so I assume no useful data is preserved in that process. Good to confirm tho
Looking in ImageRepository.php it doesn't appear that images have their extra data stripped. Also testing it on my dev instance showed that GPS data remained in the image. Should be an easy fix since all image uploads are processed through that repository.
You could check by downloading a bunch of photos and looking at the exif data, I suppose. Someone said the other day it isn't, which would be definitely a problem. It's also possible a specific instance could not strip it, which is worth checking for your own photos. I noticed that photos seem to retain the original filename which is not optimal.
