Images corrupt after git push
I added some .png images to my git repo and then pushed them to my remote repository. I noticed that the images are in the remote repository, but they are broken.
In order to verify this, I compared the binary data for the images on my local and my remote repos. I also ran the file command on images in both repos.

Why would this be happening? I searched all over google and this site for answers but have found none.

I had this issue too - here's a generic .gitattributes that looks generally safe for php web repos that worked for me: https://github.com/Danimoth/gitattributes/blob/master/Web.gitattributes
running git check-attr --all -- path/to/png before and after adding the new gitattributes showed that the image file was originally treated as a text file, and now it's binary (note I had to commit/push the .gitattributes file for it to take effect on remote)
In case the link goes dead:
# These settings are for any web project
# Handle line endings automatically for files detected as text
# and leave all files detected as binary untouched.
# * text=auto
# NOTE - originally I had the above line un-commented. it caused me a lot of grief related to line endings because I was dealing with WordPress plugins and the website changing line endings out if a user modified a plugin through the web interface. commenting this line out seems to have alleviated the git chaos where simply switching to a branch caused it to believe 500 files were modified.
