Acrobat and Signatures: "This image file is corrupt"

Hi all. I'm trying to sign a document on behalf of a colleague. When I upload their signature via "FILL AND SIGN YOURSELF" as a .jpg or .png I get "This image file is corrupt" in a red box. In attempting to do this I've now removed my own signature, and when I re-up that file, I get the same message. So it is clearly not the image files. Tried rebooting the computer (MacBook Pro) and I have also tried moving the files to my desktop... no dice. What is going on here please?!

Did that. Same problem. Adobe sucks and their "support" team is too lame to respond.

Same issue! Why is no one responding from Adobe to this clear problem?

I’m having the same problem others have reported. Acrobat keeps saying my image is “corrupted” when I try to attach my signature. I already uninstalled and reinstalled Adobe, but the issue is still there. What’s strange is that it accepted one image signature but rejected another.

It looks like this might be a wider issue with the latest version of Acrobat — something to do with how it handles signature images. Please fix this.
