Thanks Quinn, I see it.
Gina, that line is also visible in the file you uploaded to AstroBin, called “GeckoHorizontalTIFF copy.jpg”.
I checked that file straight from storage, where AstroBin copies it byte by byte, not changing anything.
So there are 3 options:
The upload got some bits flipped randomly. Extremely rare, almost impossible. Upload it again as a new revision if the file looks good on your computer.
The file looks good on your computer but the browser displays this issue. To see if this is the case, open your GeckoHorizontalTIFF copy.jpg directly with your browser on your computer. You can drag and drop the file from your file system to your browser, to verify.
The file actually has that yellow line and you didn't notice. Please verify GeckoHorizontalTIFF copy.jpg locally again.
Hope this help and please let me know what you find!
Thanks,
Salvatore
