How To Add Images To A GitHub Wiki

Every GitHub repository comes with its own wiki. This is a great place to put the documentation for your project. What isn’t clear from the wiki documentation is how to add images to your wiki. Here’s my step-by-step guide. I’m going to add a logo to the main page of my WikiDemo repository’s wiki:

First clone the wiki. You grab the clone URL from the button at the top of the wiki page.


$ git clone
Cloning into ''...
Enter passphrase for key '/home/mike.hadlow/.ssh/id_rsa':
remote: Counting objects: 6, done.
remote: Compressing objects: 100% (3/3), done.
remote: Total 6 (delta 0), reused 0 (delta 0)
Receiving objects: 100% (6/6), done.

If you look in the cloned wiki’s repository you’ll see your pages as markdown files:

$ cd

$ ls -l
total 2
-rw-r--r--+ 1 mike.hadlow Domain Users 29 Mar 20 10:29
-rw-r--r--+ 1 mike.hadlow Domain Users 27 Mar 20 10:29

$ cat
Hello this is the main page
$ cat
Welcome to the WikiDemo wiki!

Create a new directory called ‘images’ (it doesn’t matter what you call it, this is just a convention I use):

$ mkdir images

Then copy your picture(s) into the images directory (I’ve copied my logo_design.png file to my images directory).

$ ls -l
-rwxr-xr-x 1 mike.hadlow Domain Users 12971 Sep 5 2013 logo_design.png

Commit your changes and push back to GitHub:

$ git add -A

$ git status
# On branch master
# Changes to be committed:
# (use "git reset HEAD <file>..." to unstage)
# new file: images/logo_design.png

$ git commit -m "Added logo_design.png"
[master 23a1b4a] Added logo_design.png
1 files changed, 0 insertions(+), 0 deletions(-)
create mode 100755 images/logo_design.png

$ git push
Enter passphrase for key '/home/mike.hadlow/.ssh/id_rsa':
Counting objects: 5, done.
Delta compression using up to 4 threads.
Compressing objects: 100% (3/3), done.
Writing objects: 100% (4/4), 9.05 KiB, done.
Total 4 (delta 0), reused 0 (delta 0)
333a516..23a1b4a master -> master

Now we can put a link to our image in ‘Main Page’:


Save and there’s your image for all to see:

Yeah! Lots of other sites had instructions that just didn't work. Yours did so thanks a bunch!

This did not work for me. I had to add the following to the image URL:

So the final text would be: [[blob/master/images/logo_design.png]]

What I've learned from you are:
1. Wiki of a project (or repository) can be a standalone repository.
2. Clone the Wiki to local computer so we can "mkdir image" like a normal repository.
3. commit and push , so the wiki repository has its own folder of pictures.
4. Then certainly you can show them in your wiki page.

Thank you very very very much!

This was on point. Thank You

this is ridiculously involved to upload a single image. thanks for the article.

If you use subdirectories like I do when editing my wiki locally, you will need to update the path. It's easiest to just always remember a leading slash: [[/images/path/to/image.ext]]

It worked perfectly. However, I'm trying to add another image in the same file and it appears a red linked instead of the new image. May I know to solve this? Thank you

Oscar Canek said...

It's possible to do the same but with a .mediawiki file?

Thanks - still useful, should be a heads-up for the git team that the UX needs to be tweaked on that section :)
