    Testing paste via imgur

    Okay, so this isn’t a very pretty photo, but I chose it on purpose because it’s super noisy, and any new compression artifacts would show up right away.

    In #1, I used our image uploader, which reduced the size by 50% (even though my file was well under the 2MB limit), and introduced a LOT of noise.

    Specifically, the image was at 2566×1494, and was uploaded as 1024×576. That’s gruesome, but the compression is even worse than the rescaling. That’s an ugly, ugly upload.

    In #2, I uploaded the photo to imgur, right-clicked to copy it, then pasted it directly into the post. BOOM! Full size, baby.

    The disadvantage is that the pasted image doesn’t open into our lovely full-screen image viewer….but the fact that our full-screen image viewer is blowing back up an image that has been reduced by 50% in size and compressed using who knows what makes that feature not exactly useful either.

    However, right-clicking on the larger image and selecting “Open in New Window” works dandy, and looks pretty darn good.

    I’m still working through this, and invite other folks to upload and test this too! And hey, now that I’ve figured out that copy-paste works for pasting full-size images, I may actually upload a photo that I like, instead of one that I chose specifically because it was already pretty bad. Rofl

    And I do highly, highly recommend getting a free imgur account. I use it all the time for copy-paste processes like this, and other stuff too. It’s fast, easy, and non-invasive. You’ll dig it.

    Very clever Tim. I’ll have to try that out.

    The goal is obviously to rework our image processing to not degrade the images in the first place, but hey, I have no idea where the bottleneck is yet, or how hard it’s going to be to rewire.

    But the imgur solution works today, and is really only a couple of clicks longer than the direct upload process. A workaround that works is a lovely thing to use while we wait to develop the proper long-term solution!

    Update! I’ve found where in our settings we were mashing the images, and we are now NOT mashing them. Sunglasses

    Again noting that I chose this image because of the super-noisy clouds and gradients galore, and NOT because I think this is an especially pretty picture, but I love that it’s not being chewed up.

    For the record, there is pixel-accurate lossless compression on the largest images. Our admin tools include a wipe tool that allows you to slide it back and forth to compare, and I can say that on a full-size, very bright 4K display, I really can’t see a difference. Click on it to see full size in the lightbox.

    And of course see what you see with your own images!

    Okay, the good news is that the compression is visually lossless. The somewhat exasperating news is that even though I’ve checked “do not scale”, there is a very slight rescaling. I think I can live with this, though!

    I do encourage other folks to check this out with their large images, including cover images for their member profiles. MUCH better!
