+#+TITLE: How To Set An Image Title In Hugo Using Org-Mode Markup
+#+DATE: 2020-06-24T19:50:03-04:00
+#+DRAFT: true
+#+DESCRIPTION: How to set the title or alt text of an image in hugo using org-mode markup
+#+TAGS[]: hugo org-mode
+#+KEYWORDS[]: hugo org-mode
+#+SLUG:
+#+SUMMARY:
+
+One of the differences between using markdown and org-mode markup for
+writing Hugo pages is how you set the alternative text and title of an
+image.
+
+In markdown, you would write it as
+#+BEGIN_SRC
+![alt text](dummy-image.png "Image Title")
+#+END_SRC
+
+Where in org-mode, typically you would use a caption like this
+
+#+BEGIN_SRC org
+#+CAPTION: Image Title
+[[file:dummy-image.png]]
+#+END_SRC
+
+and that would be the end of it. However in Hugo, if we use that
+format, we end up with this
+
+#+CAPTION: Image Title
+[[file:dummy-image.png]]
+
+with the following HTML
+
+#+BEGIN_SRC html
+<figure>
+  <img src="dummy-image.png" alt="dummy-image.png" title="dummy-image.png">
+  <figcaption>
+    Image Title
+  </figcaption>
+</figure>
+#+END_SRC
+
+With the caption being put into a figure, and the image's alt text and
+title being set to the URL of the image, which isn't very helpful
+for people using screen readers, or if the image fails to load. It
+also takes up room with text we normally wouldn't be showing unless
+the image was being hovered over.
+
+If we give the org-mode link a title, it just turns into a regular
+link to an image instead of embedding it
+
+#+BEGIN_SRC org
+[[file:dummy-image.png][Image Title]]
+#+END_SRC
+
+[[file:dummy-image.png][Image Title]]
+
+resulting in this HTML
+
+#+BEGIN_SRC html
+<a href="dummy-image.png">Image Title</a>
+#+END_SRC
+
+
+The way around this is to use the ~#+ATTR_HTML~ element in
+org-mode. You use it in the format of ~#+ATTR_HTML: :<attr>
+<value>~. So to add a title and alt text to an image, you would add
+
+#+BEGIN_SRC org
+#+ATTR_HTML: :alt alt text
+#+ATTR_HTML: :title Image Title
+#+END_SRC
+
+Above the embedded image, resulting in
+
+#+BEGIN_SRC org
+#+ATTR_HTML: :alt alt text
+#+ATTR_HTML: :title Image Title
+[[file:dummy-image.png]]
+#+END_SRC
+
+Which finally outputs what we want
+
+#+ATTR_HTML: :alt alt text
+#+ATTR_HTML: :title Image Title
+[[file:dummy-image.png]]
+
+giving us this HTML
+
+#+BEGIN_SRC html
+<img src="dummy-image.png" alt="alt text" title="Image Title">
+#+END_SRC
