Danbooru

Imageboard Samples

Posted under General

Recently came across:

(For whatever reason, linking these tags with {{}} breaks formatting/doesn't work..)

Considering these kind of samples shouldn't really be uploaded, should they be deleted/flagged & full-size image uploaded, or simply just put as the child of the full-size post?

And since it's somewhat related, should the same be done for source:http://lohas.nicoseiga.jp/thumb/* ?

Updated

regarding the use of {{}}, try these:

i would assume it has something to do with escaping the slashes.

and regarding the topic at hand, do we have an official tag for smaller versions of posts outside of pixiv? or a tag isn't necessary to identify them?

i'm in favor of not encouraging uploading smaller versions and flagging (if higher versions are available) them just like their pixiv counterparts.

I think that resized should cover it.

How would you use filename: here? For things uploaded to Danbooru without a source, only the md5 hash is retained (and you can use md5: if you need to), for those with a source, source: includes the filename, and works with wildcards, which should do what you would need.

For images with a source, yes, source: should be able to find everything.

Problem is if the sample lacks a source URL, there is currently no way to actually know that it's a sample (Like the image I posted above )

filename: could be useful for a few reasons.
yande.re for instance, saves samples as "yande.re ID sample.jpg" by default. Meaning something along the lines of filename:yande.re_*_sample.jpg could return all sample images without a source (Unless the file was renamed by the uploader).
If it isn't retained though, not really any way to figure if it's a sample or not.

md5: is useless for finding sample images considering the API doesn't provide the MD5 of the sample image, only the full-size.

Most of these images could be found by sending them through IQDB, but would rather avoid checking 200K~ full-size images just to find samples.

I see what you want to do, but unfortunately the original filename is discarded unless it's included as part of the source (and even then, can easily be tampered with after the fact).

This isn't any different than pixiv thumbnail/pixiv manga sample, so they should be deleted when the full size also exists on here.

We should make one. Lump all four sites (and whatever else may follow; excluding pixiv) under imageboard sample or image sample?

This is a special case of that, with a particular resize--generated by the hosting site--and a full size easily available. Perhaps this new tag (and pixiv thumbnail/pixiv manga sample, for that matter) can imply resized instead.

Not that I know of. Went ahead and made a ticket for it. If it's called for (by jxh2154), it would be easy (if a bit slow) for me to do a massive tag edit setting the source of all sourceless posts to "none", so that "source:none" would appear to work like parent:none does. Given the ~115k bad id edits I've already made, I suppose this wouldn't be that much of a stretch for me, lol. It'd be a lot faster and easier to maintain, too. I'll ask Albert if he can add this feature the smart way, though.

EDIT: Created a separate thread for source:none.

This would be extremely useful, currently just using my own copy of the DB to find these images. It isn't as friendly, but it works as needed.

Another url I'm not sure about.. source:*.moe-ren.net/gazo/remod/files/*
Found post #833288 which is the same size as the sample for this, yet it has a (dead) source. Considering the URL has a lot of images from different artists I'm assuming it was some kind of imageboard. Can anyone verify?

Also, post #795446 is a sample (Filesize is same as sample filesize) yet it has the same resolution, should the original still be uploaded when this is the case?

Huh? Danbooru's size is 302.9 KB. Konachan sample is 525.7 KB. (Konachan full is 1,064.1 KB)

The only thing I care about is the MD5 hash. If the hash matches the sample and not also the full size, it's fair game. But if the hash doesn't match the sample, it isn't the exact same image as the sample, so it's just a simple duplicate, not imageboard sample, and duplicate isn't enough justification to flag something.

Linked to that since it seems to be the original origin of where it posted from, every other imageboard I've checked with the image had "imageboard" as the source.

It seems to have been uploaded from Sankaku which also has the source as "imageboard".
Also considering the MD5:
Danbooru's MD5: 7882912591e4faf6b3645e20bb6d990b
yande.re's MD5: c1f52c54a167e2549e6cd9f29736a9a5
Konachan's MD5: 8a384c730e7ea6a1b6c9c9c9197869ee

Sankaku's A MD5: c1f52c54a167e2549e6cd9f29736a9a5
Sankaku's B MD5: 7882912591e4faf6b3645e20bb6d990b (This looks like sample image)

Can't seem to find the origin of where it was Sankaku's version was originally uploaded though, and it doesn't seem to be the sample of Konachan/yande.re.
Going by size though, 302KB~ looks like a sample, compared to the full-size versions yande.re/Konachan/Sankaku1 has.

Edit: After a bit more investigation it seems like Sankaku B was posted before the rest, yet it has the "imageboard" source.. No idea what imageboard this could be..

Updated

So it's not an imageboard sample. It's the full size of Sankaku-B, not the sample size of Sankaku-B. That there are other, larger versions elsewhere (even on Sankaku itself) is beside the point. What a mess, once you start tangling with rehost sites.

For something like the source:none it would be good to get confirmation from Albert first, just in case anything goes wrong and he needs to undo it, but the idea is sound in my opinion. I have no objections.

Found something else I'm not sure what to do with.
http://danbooru.me/post/show/1174700 seems to be a (Possible) sample of this .
Full-size is 2126x3027, which would make the sample 1054x1500 (Same as the image).

Problem is the image has been deleted, meaning there is no way to make an exact comparison. Although it seems a bit odd that the size is exactly the same as what the sample would be.

Should these images be deleted like the rest of the samples, with the full-size uploaded? or simply just left since there is no image to make an exact comparison to?

try this for the deleted, maybe: https://yande.re/jpeg/86b882e53c35a79baae42750a0139378.jpg

it appears the hashes don't match?

That is the full-size JPEG version.

Although just noticed that I didn't change .PNG > .JPG for the sample URL, meaning this is the sample, which seems to be an exact match to the image uploaded. Considering this has a completely separate source, might have to keep an eye on this site..

Just a fyi all jpegs uploaded to yande.re get exif data stripped.

This is due to AP inserting unique identifiable information in exif data.
