Andrew s  andrew-wei answer works great  You can also chain a few together  depending on what you are trying to do  This  for example  gets you an image with alt  title and caption with a line break and bold and italics in different parts of the caption    img   br   strong  margin-top  5px  margin-bottom  7px  font-style italic  font-size  12px    img   br   strong   em  margin-top  5px  margin-bottom  7px  font-size  12px  font-style italic     With the following  lt img gt  markdown     description  https   img jpg  description      Image      description

If you don t want to use any plugins  which means you can push it to GitHub directly without generating the site first   you can create a new file named image html in  includes    lt figure class  image  gt     lt img src     include url     alt     include description     gt     lt figcaption gt    include description    lt  figcaption gt   lt  figure gt    And then display the image from your markdown with      include image html url   images my-cat jpg  description  My cat  Robert Downey Jr

For Kramdown  you can use   refdef  style  quot text-align  center  quot   to align center   refdef  style  quot text-align  center  quot     example  https   upload wikimedia org wikipedia en a a9 Example jpg    width  quot 50  quot   shadow     refdef    refdef  style  quot text-align  center  quot    Fig 1  This is an example image   Source  https   upload wikimedia org wikipedia en a a9 Example jpg      refdef

The correct HTML to use for images with captions  is  lt figure gt  with  lt figcaption gt    There s no Markdown equivalent for this  so if you re only adding the occasional caption  I d encourage you to just add that html into your Markdown document   Lorem ipsum dolor sit amet  consectetur adipiscing elit      lt figure gt     lt img src    site url   assets image jpg  alt  my alt text   gt     lt figcaption gt This is my caption text  lt  figcaption gt   lt  figure gt   Vestibulum eu vulputate magna      The Markdown spec encourages you to embed HTML in cases like this  so it will display just fine  It s also a lot simpler than messing with plugins   If you re trying to use other Markdown-y features  like tables  asterisks  etc  to produce captions  then you re just hacking around how Markdown was intended to be used

Here s the simplest  but not prettiest  solution  make a table around the whole thing  There are obviously scaling issues  and this is why I give my example with the HTML so that you can modify the image size easily  This worked for me      lt img src    alt    style  width  400px    gt      My Caption

lt p align  center  gt     lt img alt  img-name  src   path image-name png  width  300  gt     lt br gt       lt em gt caption lt  em gt   lt  p gt    That is the basic caption use  Not necessary to use an extra plugin

There are two semantically correct solutions to this question    Using a plugin Creating a custom include   1  Using a plugin  I ve tried a couple of plugins doing this and my favourite is jekyll-figure   1 1  Install jekyll-figure  One way to install jekyll-figure is to add gem  jekyll-figure  to your Gemfile in your plugins group   Then run bundle install from your terminal window   1 2  Use jekyll-figure  Simply wrap your markdown in    figure    and    endfigure    tags   You caption goes in the opening    figure    tag  and you can even style it with markdown   Example      figure caption  Le logo de   Jekyll   et son clin d oeil    Robert Louis Stevenson           Le logo de Jekyll   assets images 2018-08-07-jekyll-logo png     endfigure      1 3  Style it  Now that your images and captions are semantically correct  you can apply CSS as you wish to    figure  for both image and caption  figure img  for image only  figcaption  for caption only    2  Creating a custom include  You ll need to create an image html file in your  includes folder  and include it using Liquid in Markdown   2 1  Create  includes image html  Create the image html document in your  includes folder     lt  --  includes image html -- gt   lt figure gt         if include url         lt a href     include url     gt         endif         lt img            if include srcabs                src     include srcabs                else                src     site baseurl    assets images    include src                endif        alt     include alt     gt         if include url         lt  a gt         endif           if include caption             lt figcaption gt    include caption    lt  figcaption gt         endif     lt  figure gt    2 2  In Markdown  include an image using Liquid  An image in  assets images with a caption   This is  Jekyll  https   jekyllrb com  s logo       include image html     src  jekyll-logo png   lt  -- image filename  placed in  assets images  -- gt      alt  Jekyll s logo   lt  -- alt text -- gt      caption  This is Jekyll s logo  featuring Dr  Jekyll s serum    lt  -- Caption -- gt       An  external  image using an absolute URL   change src    to srcabs      This is  Jekyll  https   jekyllrb com  s logo       include image html     srcabs  https   jekyllrb com img logo-2x png   lt  -- absolute URL to image file -- gt      alt  Jekyll s logo   lt  -- alt text -- gt      caption  This is Jekyll s logo  featuring Dr  Jekyll s serum    lt  -- Caption -- gt       A clickable image   add url    argument   This is  Jekyll  https   jekyllrb com  s logo       include image html     src  https   jekyllrb com img logo-2x png   lt  -- absolute URL to image file -- gt      url  https   jekyllrb com   lt  -- destination url -- gt      alt  Jekyll s logo   lt  -- alt text -- gt      caption  This is Jekyll s logo  featuring Dr  Jekyll s serum    lt  -- Caption -- gt       An image without a caption   This is  Jekyll  https   jekyllrb com  s logo       include image html     src  https   jekyllrb com img logo-2x png   lt  -- absolute URL to image file -- gt      alt  Jekyll s logo   lt  -- alt text -- gt       2 3  Style it  Now that your images and captions are semantically correct  you can apply CSS as you wish to    figure  for both image and caption  figure img  for image only  figcaption  for caption only

I know this is an old question but I thought I d still share my method of adding image captions  You won t be able to use the caption or figcaption tags  but this would be a simple alternative without using any plugins   In your markdown  you can wrap your caption with the emphasis tag and put it directly underneath the image without inserting a new line like so       path to image   image caption    This would generate the following HTML    lt p gt       lt img src  path to image  alt gt       lt em gt image caption lt  em gt   lt  p gt    Then in your CSS you can style it using the following selector without interfering with other em tags on the page   img   em       Note that you must not have a blank line between the image and the caption because that would instead generate    lt p gt       lt img src  path to image  alt gt   lt  p gt   lt p gt       lt em gt image caption lt  em gt   lt  p gt    You can also use whatever tag you want other than em  Just make sure there is a tag  otherwise you won t be able to style it

A slight riff on the top voted answer that I found to be a little more explicit is to use the jekyll syntax for adding a class to something and then style it that way   So in the post you would have     My image   images my-image png      image-caption   The caption for my image    And then in your CSS file you can do something like this    image-caption     text-align  center    font-size   8rem    color  light-grey    Comes out looking good

You can try to use pandoc as your converter  Here s a jekyll plugin to implement this  Pandoc will be able to add a figure caption the same as your alt attribute automatically   But you have to push the compiled site because github doesn t allow plugins in Github pages for security
