Images not being added to `gh-pages` branch

[valerahime]

I've ported a WordPress blog to Jekyll using jekyll-action@2.4.0 and wanted to make a new blog post to test the functionality. I added an image to assets/images/2022/09/_DSC0086.jpg, referenced it in said blog post, and commited to GitHub.

For some reason, the image isn't being added to the gh-pages branch at all. It's in the main branch just fine:

But not in the gh-pages branch:

I really don't know what the issue could be, or if this action is even where the problem is. I didn't see any specific settings I had to use, and the images I uploaded when I first made the blog worked without issue.

Here's the workflow file, I just copied and pasted it:

name: Build and deploy Jekyll site to GitHub Pages

  push:
    branches:
      - main # or master before October 2020

jobs:

      - uses: actions/cache@v2
        with:
          path: vendor/bundle
          key: ${{ runner.os }}-gems-${{ hashFiles('**/Gemfile') }}
          restore-keys: |

        with:                                # Some relative inputs of your action
          token: ${{ secrets.GITHUB_TOKEN }}

Never mind, I realize I had an underscore in the filename, which is ignored.
