Given that catbox and pic8 both accepted it, I wouldn't think it's corrupted. I'm not sure how doing it from the pic8 site vs from the poal page.
I just tried pasting from clipboard, it didn't work for me. I tried the original image and it said it was too large, so I tried the smaller image and I got that same "image file invalid" error. To do this test, I copied the image from where it's already hosted on pic8.
Given that ...pic8....accepted it,
Oh I thought it wasn't working even when uploading on pic8
I'm not sure how doing it from the pic8 site vs from the poal page.
Then it might be a pic8 API issue.
---> pic8 is being gay again!
