Something wrong that isn't right.

[Krikor]

Hello everyone, News!

Following PixLab's suggestion: 

"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 make a difference No... but we never know, in all cases that's the one we all tried with positive opening in GIMP ";

"Maybe try to re-download it, could be a hick-up during your first download ";

So, I downloaded the image that I uploaded here to G.F-N and when I opened it in my GIMP the image simply displayed the spider!

I confirm.
Somehow, the same image that I downloaded before and that did not display the spider in my GIMP, when I downloaded it again here from the forum (where I had uploaded it without any changes) and opened it in my GIMP... the spider in this time is displayed.

I don't know what happened, but I was right when I chose the title "Something wrong that isn't right."

Thanks to everyone for helping in the investigation of this case!
