I love u/the_picard_maneuver but I don't love that I can't just tap their posts to view the image in the browser, have to click the link and leave Lemmy to see them.
You do? Hmm, that's strange... I'm uploading everything through Lemmy directly and haven't been hosting off site.
When I switch to my .world account, it doesn't appear that way to me either. Could anyone more technical take a stab at what might be happening?
The problem is something to do with startrek.website, but it only affects the default UI (Lemmy-UI). I've seen it on a large number of images uploaded on startrek.website but viewed on another instance. It doesn't seem to affect files uploaded to external websites though
I think it's something about HTTP cross-origin headers that they've configured incorrectly. I'll have to confirm later when I'm on a desktop browser.
Edit: It's actually uBlock Origin blocking the images from loading! There's a rule in EasyList that is matching *.website (it's a lot more complicated of a rule, but that's the gist). It blocks it unless it's coming from one of a few whitelisted pages like lemmy.world.
I found a workaround mentioned here: https://lemm.ee/comment/3068996
That's more complex than I understand so I'll take your word lol
All I know is instances have what look to be old links to media that gets fixed whenever you clear cache
Yeah, that's what I suspect too.
Oh interesting... Yeah, I mostly post from Liftoff or Voyager on my phone, so I wouldn't have noticed.
I wonder if the startrek.website admins are aware of the inconsistency.
I think I mentioned it to one of them, but I don't know if they know the extent or if they're just working on it
No issues for me. Using Memmy.
Doesn't cause it on the sync app for me. All your uploads show up without a website.
No issues on Jerboa
Clearing my Firefox cache after adding lemm.ee and startrek.website to my uBlock whitelist fixed the issue. Now I can see your wonderful posts easier!
Great news!!
I assumed it was something to do with lemm.ee's policy with federating images to protect against CP attacks, since everyone else who says they're having trouble is also from lemm.ee. I think what they're doing is just linking to the other instances' images directly, and maybe startrek.website doesn't like that?
I can see your lemmy.world account's posts just fine.
That might be it. On top of not federating images, I know that Lemm.ee has file size restrictions for its users too (to reduce load and keep things fast, I think), so maybe there's something related to that as well.
You can fix it by clearing your cache or by using a different client like voyager or photon
Clearing Firefox cache after adding lemm.ee and startrek.website to ublock whitelist fixed the issue. Thanks :)
No problem!
Yeah startrek.website doesn't technically allow hotlinking, which lemm.ee is doing.
The thing is, apps just ignore that hotlink forbiddance, while browsers respect it. And other instances federate images.
