"Image/video appears corrupt"

[ccd0]

4chan X version 1.13.8.8
FF version 48.0.2

Any image or video submitted, even ones I've posted before, now generate a "Image appears corrupt" error message. Just started this morning a few hours ago, and was posting happily maybe a day ago. Might be on their end...?

[krackers]

Something similar happens when I try to upload an image by copying it in. Whereas before it would upload and show a nice thumbnail, not it shows something like:

And submitting the post fails.

Any errors in the console (also check the browser console -- Shift+Control+J if Firefox)? @krackers, are you also using Firefox, and if so, what version? Does it happen in a fresh profile?

[krackers]

@ccd0 No, Chrome 59.

I'm getting the following when I try to paste an image. I'm guessing 4chan changed their CSP headers?

boards.4chan.org/:1 Refused to load the image 'blob:https://boards.4chan.org/7d1ce5a3-ef2a-43ff-8a7f-54245b2f4376' because it violates the following Content Security Policy directive: "default-src 'self' * data: 'unsafe-inline' 'unsafe-eval'". Note that 'img-src' was not explicitly set, so 'default-src' is used as a fallback.

EDIT: Submitting the image started working after restarting chrome. It's only the thumbnail display that's problematic.

I'm hesitant to switch to a new profile for testing because last time I tried Chrome decided to wipe all my bookmarks. Switching to incognito the issue still persists, however.

EDIT 2: It turns out adblock was the reason for this. My issue is therefore invalid.

The easylist filter includes the following: *$csp=default-src 'self' * data: 'unsafe-inline' 'unsafe-eval'. I can unblock this manually for 4chan.

I can unblock this manually for 4chan.

how?

i don't know how to do that.

i'm also having this issue.

firefox portable esr 38.7.1
4chan x 1.1.13.8.8
adblock plus 2.8.2
easylist 20170624

post any image
"x.png: Image appears corrupt
[delete post] [delete all]"

there's no preview of the image in the image queue.

i can still post the images.

yeah, but it's still a pain.

the main issues with this; if they're not obvious.

can't see previewed images in image queue
you get flooded with -
"x.png: Image appears corrupt"
"[delete post] [delete all]"
every time you queue an image

i can't disable filters individually for individual sites on adblock. or it's not immediately obvious to me.

i can click on the adblock icon and select "disable on boards.4chan.org" when i'm on the thread page.

i can use ublock, noscript, ghostery, peerblock portable, etc. instead.

but i'd like to have adblock remain on for this page and every page.

i'd like to know know how to do this. just in case if it's needed in the future. or if anyone doesn't want to - or can't - run more than adblock, etc..

also i was having issues uploading an image to post on here.

drag and drop an image
"something went really, really wrong"
manually browse and upload image
"something went really, really wrong"
turn off adblock
manually browse and upload image
works
drag and drop an image
"something went really, really wrong"
turn adblock back on
go to a new page
can upload images here normally

i don't know what the hell is going on with that. but. just in case that's related. putting it out there.

too long; didn't read:

thanks to ccd0 for keeping this issue open.

please help me.

I have the same issue. Chrome 59 with uBlock Origin

This works but it would be a good idea to report this to https://forums.lanik.us/viewforum.php?f=64.

I am using ABP. I did exactly that, restarted the browser (Firefox), it's not working.

[d3athrow]

I am receiving the same issue as of a few days ago and it still persists with every addon except greasemonkey disabled.
FF v55.0b3

Content Security Policy: The page’s settings blocked the loading of a resource at blob:http://boards.4chan.org/dc8c26b2-6be2-4da7-ae23-cee12c91111d (“default-src http://boards.4chan.org * data: 'unsafe-inline' 'unsafe-eval'”).

@d3athrow
That's very odd, since that specific setting in your error message is known to come from EasyList. I would double check that you are seeing it with your ad blocker off. Maybe you forgot to reload the page?

if you want to be more specific. Not sure precisely what it's blocking, probably something related to the obfuscated ad script now included in the page itself.

If you have uBo on at all, you need to add the filter in #1417 (comment). Whitelisting 4chan won't work.

[ccd0]

I think the previous reply is wrong as whitelisting without adding the filter appears to work for me. Filter still the best approach, though.

[d3athrow]

Filter fixed it for me, thanks.

[phaux]

Anybody reported it to ublock/adblock plus devs yet?

[krackers]

@phaux It's not a ublock issue. It's a filter issue.

[phaux]

@krackers ...and they bundle these filters by default

[Lapan]

ABP Filter works for images but not for WEBM's

Copy/pasting the comment in #1447 into ublock origin didn't work for me. It wouldn't accept it.

[deadman3000]

The problem is back and none of the above fixes it.

[ccd0]

@deadman3000
Are you sure you have the recommended filter set? uBlock Origin recently switched to the WebExtensions system causing all users' settings to be reset.

#1441
Submitter: Some Anonymous Guy
Whenever I try to post an image regardless of file extension the message "X.jpg/png/gif: Corrupt image or error reading metadata. [More info]
[delete post] [delete all]" pops up. At first I thought it was just a problem on my end (and panicked because I thought my 4chan folder was corrupt) but later on I saw other users have the same complaint.
I've tried adding "@@||4chan.org^*$csp=default-src 'self' * data: 'unsafe-inline' 'unsafe-eval'" to ublock origin at the suggestion of another user that managed to solve his problem by doing so but it still didn't work.
I've also tried updating to the newest 4chanX release but it still displayed the same message.
Also, my post timer gets sometimes stuck at either 5 or 12 seconds, closing the reply form and reopening it seems to solve the issue but it's been happening more frequently lately.
Any suggestions on what could be wrong?

Kein:
Same here, Vivaldi 1.1x, latest 4chanX, all Webms show this error

[tidux]

The uBlock Origin filter no longer works on nightly. This makes 4chanX completely unusable since I'm not turning off uBO entirely with the coin mining scripts around.

UPDATE: the following filters in uBO fixed it

Just updated from FF52 ESR to FF61 and got that, and @tidux 's filters didn't fix it.
uBO, tampermonkey beta.

[tidux]

I've had issues with Tampermonkey on Firefox (although oddly, not on Edge). Try Violentmonkey

I've tried Violentmonkey before on FF52 but it made the browser really slow. Anyway, I tried Violentmonkey and I still get the corrupted message.
