Something wrong that isn't right.

I did find 3 different png of the "same" image, all of them with different size and quality, all of them smaller than the one you did put in your first post.

I did stop there to search as I go thru so many pages already, but none of them match 100% yours.

Some solutions to investigate?
Maybe try with the one you uploaded on G-F? direct link > https://www.gimp-forum.net/attachment.php?aid=12366 , why try with it? because it's on a Linux server and it would be interpreted by Firefox, should it makes a difference? No... but we never know, in all case that's the one we all tried with positive opening in GIMP  
If you could recall the page and give us the link it would be nice for us to test with the original, or maybe it was just a temporary download problem on your side?

PixLab,

I checked my browsing history and found the link:
https://www.google.com/url?sa=i&url=http...AdAAAAABAE

Ok, I will try with the link you posted regarding the file I uploaded. If there is any change then I will comment here in the forum.

Yes the mode is indexed. I checked the channels too and they are indexed and alpha. Turn the eye off the alpha channel and you get a black square. Turn the indexed channel off and the black spider remains.
*Threshold Alpha (under layer - transparency) at value one turns the spider invisible.

Hi Sally,

The difference here is that nothing changes if I turn off the indexed channel.

With Threshold Alpha, as you mentioned, nothing changes here, regardless of the adjustment I make to the values. From zero to one the image remains unchanged.

Thank you for helping with the investigation.
