Image Replacement Request Thread

Oh. I just ran them through imagemagick and apparently at same height they have a single pixel of difference in width. It was impossible to notice in browser. Should I just upload the larger one and set it as parent?

These images are not the same.

Where? They look the same to me, except for sharpness and aliasing, both caused by the difference in resolution. I see a few hotspots of differences at the tips of the tails, but they seem to be caused by aliasing.

The current post #2446836 is one pixel too narrow, though. The width should’ve been rounded to 1657 instead of 1656. The aspect ratio of the large version pretty much exactly matches the old post #2446836 before it was replaced.

Not sure why it wasn't automated.

Also, I have a situation that I'm unsure about: pixiv #58308768 has post #2151686 and post #2118042 (at least), which were uploaded from Twitter. They are PNGs, and I've confirmed that they're pixel-for-pixel identical -- in the case of those two posts, at least -- but the ones from pixiv are better compressed (smaller filesize for the exact same image) and have slightly more metadata. Since the images are the same, it's definitely not worth uploading and parenting IMO. Should we replace the images? They pixiv ones really are superior in every way, and there's nothing to be lost by getting rid of Twitter's versions, although there's also not very much to be gained. I hesitate, however, to set a precedent of replacing from a different source because that can be catastrophic if not done very sparingly and very carefully. Thoughts?

You wouldn't be setting a precedent, unfortunately.
