    Image Quality of Generated Thumbnails from Image Machine - part deux

    I am having issues with the Image Machine creating some pretty bad looking thumbnails. The original images are line drawings. The first round of drawings were JPGs - they look awful, very digitized. So I suggested trying PNG's, they only look slightly better. The different is very noticeable because I'm having some issues with a conditional that is supposed to show either the thumbnail or an "image coming" thumbnail. Instead it seems to want to pull in the full size 1000 x 1000 image into a constrained space. That image looks perfect, exactly what I want the generated thumbnails to look like. I checked the Upload Settings and it's set to 100% but it also "JPEG Image Quality"

    You can go here then look at the differences. I was surprised when I went back to the page one of the thumbnails looks good but I can't find it on the server. Then if you look at the thumbnail for B15, it's awful.

    Another question - is Cloudflare stilling screwing with these images? I try yo look at one of them in different browsers - Chrome is showing the WEBP extension while Firefox still shows PNG. I thought flushing the cache at Cloudflare should have cleared these out?

    All I want is a good looking thumbnail - do I have to go back to making them myself?

    Hey Leslie,
    So the problem is that the jpegs you've uploaded are in "Indexed color" rather than RGB/8 Bits/channel. I'd take all of the original images you have and run them through RIOT or another batch processor before uploading again. I did a little test....

    The image on the left was generated using the original file. The center image was generated using an updated jpeg I saved in RGB mode.


    Hope this helps!

      Thank you Ryan, I never would have caught this for a couple of reasons but what you are showing reminds my of a GIF (index) image. I will pass this on to the store owners, so they can pass it along to who they have creating these images.

        On an additional note, the image I previously mentioned has been updated to a PNG. I did try to take a peek at another image via Photoshop but it can't even open it. My Mac's Preview Info shows the document type is in deed a GIF although the extension is JPG. But it says the color mode is RGB. I'm thinking whomever created these images may have made them as GIF's but changed the extension to JPG. I say this because as soon as I changed the extension to GIF I could open it in Photoshop.
