Answer 1

First you'll want to add the files in question so that they're tracked by Git (you don't have to commit any changes, but Git needs to know about the files):

git add pages/memclub/images/subheaders/leadership.png pages/memclub/images/subheaders/male.png 
git add pages/memclub/images/subheaders/marketing.png pages/memclub/images/subheaders/training.png

Then you can stash your changes:

git stash 

When you're ready to start working on the files again, you can use:

git stash pop
