PSA: downloading from tumblr
TL;DR if you're saving images from tumblr, change "1280" to "raw" in the url first!

If you're like me, you care about having the highest quality images (and if you're not like me, shame on you).

Tumblr is stupid and frustrating in that it resizes everything that's uploaded to it. If the filename ends in _540.png or _1280.png then you've saved a smaller, resized version instead of the original image, and that's bad. Most image downloaders are going to grab the 1280 version, because that was thought to be the biggest one available. But it turns out you can obtain the raw, unresized image by replacing the 1280 with "raw" in the filename.

Here's an example. Let's take a post from Zko's blog (nsfw, obviously):
http://lewd-zko.tumblr.com/post/154604029378/gardevoir-move-set-flash-hypnosis-attract

If you were to save that image, you'd probably get it from this url (open the image in a new tab to be sure):
http://68.media.tumblr.com/14e48f625bb423260a979a424857f5f5/tumblr_oicntftj2Y1ufsny6o1_1280.png

That's a much smaller version than the original. The one on the hub, uploaded by Zko himself, is 2400x1513, while that one is only 1280x807.

Replace that _1280.png with _raw.png however, and you get:
http://68.media.tumblr.com/14e48f625bb423260a979a424857f5f5/tumblr_oicntftj2Y1ufsny6o1_raw.png

Which is the original 2400x1513 file, in all its lewd glory!

Please tell all of your friends about this. Don't link to 1280 urls, and don't save them, either. If you've uploaded a _1280 version of the image in the past, do us all a favor and replace it with the raw version. Together, we can keep our boorus as high-resolution as possible.
This is some pretty good advice
Dude i am noting that down in notepad cause what i learned i gonna make sure i keep that piece of knowledge.
Mods, can we get this stickied, please?

I second that motion. If not, we need some sort of sticky PSA thread for this sort of stuff.
Tumblr's interface sucks. I joined there after TVTropes threw me out and it's just not my scene, but part of the frustration there was that awkward as hell structure that just opens blogs as frames instead of just sending me to a new url.

Yes, i'd rather browse tumblr like it was blogspot or, say, the Washington Post.

Nice to know they're also fucking with image sizes in that convoluted UI of theirs.

That's pretty solid advice! Still, "if you're like me," ...*looks at the adorably masked penis pic* I can only imagine that picture talking.

*immature giggle*
So, I noticed today that this no longer seems to work. Did tumblr change something? Are we back to only getting the 1280 versions?

It only works on some images. Likely because they were accessed while the trick still worked, and are cached in server memory. Elsewhere it looks like it was intentionally disabled.

tumblr_o7cybkmfO61twt3x6o1_1280.jpg: ok
tumblr_o7cybkmfO61twt3x6o1_raw.jpg: 404
tumblr_o7cybkmfO61twt3x6o1_asdfghjk.jpg: "Access Denied"
fhy4wi5ghuesyhg.jpg: "Access Denied"
fhy4wi5ghuesyhg_raw.jpg: 404

The servers are returning 404 errors on any URL ending with _raw.jpg, unlike all other nonexistent URLs that instead return an "Access Denied" message. This implies that the raw versions still exist, but they don't want us to see them :C

Well *that's* nuts.
Someone go complain? :v
CORRECTION! If you get a 404, you need to remove the number at the beginning of the url. Thanks, e621 wiki.

That 404 thing is still hella weird.
Necroing this thread. The format has changed again and raw links are broken.

Now you need to change "media" to "data" e.g.

http://data.tumblr.com/14e48f625bb423260a979a424857f5f5/tumblr_oicntftj2Y1ufsny6o1_raw.png
