All committers have signed the CLA.

I signed it but it's pending. I rechecked 3 times.

Hey, thanks for the PR!

While you may have signed, @CLAassistant is probably talking about the email address that your bot has used in the commit.

The GitHub account with the email address in the commit attached to it needs to sign the CLA :-)

Hi, @ghostslayer989, could you please create a single commit done by you (not the bot) or change the author of this commit to yourself, so that the CLA check can pass and we can merge this?

To change the author:

git checkout imgbot
git commit --amend --author="your-name-or-alias <your-github-email>"
git push -f

Be sure to use the same e-mail you used to sign the CLA (probably ghostslayer989@users.noreply.github.com).

Otherwise, I see no alternative except closing this and doing it ourselves.

Alright, I force pushed on your repo to update the commit author. I'm merging this now since it's already accepted.
