Preview thumbnail image not displaying properly Answered

The preview thumbnail image of my new Instructable is all distorted and it isn't possible to make out what the image shows. Also, I can't find a way of changing the thumbnail image once it is published. It's chosen the first, yellow image, not the second clear image.

Any help appreciated!
Thanks,

UPDATE: I edited something in the Instructable and when I clicked publish, it gave me the chance to reselect which image I wanted as the thumbnail. However, the preview is still darker than what it should be.

I've had a similar issue with a couple of my cover images. It's apparently a rare, but known bug.

If your image happens to be saved as a PNG, try saving it as a JPEG instead. This solved the weird darkening issue for me.

To change the cover image, make sure the image is added to the introduction in the editor and then hit save. This will land you on the cover image/keyword page, and any new images you added to the intro should now show up on the pull-down menu under the "Change Cover Image" button.

If these things don't help, let me know and we can dig a little deeper.

I've changed the image to a JPEG now and that solves it. However, it is still using the old image on my profile Instructables section - I guess it takes time for the system to update. Also, do you know where I can find where my Instructable is featured?

Thank you - I'll give that a go. My image is a PNG. I think the reason why the first one (posted above) was worse is because I clicked Publish multiple times as I though the previous clicks hadn't registered. So I suppose the current image is better because it was only distorted once.

Sometimes the parts of a PNG that look white are actually transparent, and when they get displayed in other places the transparent part is just shown as "off" by your monitor, and comes out black.

As you say, saving as a JPEG solves the issue.
