Image Shortcodes

Jake G May 19, 2021 #Features #Shortcodes #Images

This post covers the imgswap and img shortcodes. Images can also be embedded directly using markdown ![Ferris](ferris.svg), but it is better to use a shortcode so you can explicitly set the width and height, this will help prevent content layout shift which improves user experience and the google lighthouse score.

img Shortcode

src is the path and filename of the image. (mandatory)
class sets a class for the image. (optional)
alt sets the alt note for the image.
w is the width of the image.
h is the height of the image.

** google lighthouse recommends setting alt, w, and h attributes. If alt is omitted then the filename is used. If w or h are omitted then get_image_metadata() fills these values. **

Usage (same path)

{{ img(src="ferris-happy.svg" alt="Ferris is Happy") }}

Output

 
<img src="ferris-happy.svg" alt="Ferris is Happy" width="600" height="400" loading="lazy" />

Usage (relative path ./)

{{ img(src="./img/ferris-gesture.svg" alt="Ferris says Hello") }}

Output

 
<img src="img/ferris-gesture.svg" alt="Ferris says Hello" width="600" height="400" loading="lazy" />

Usage (root path /)

{{ img(src="/images/ferris.svg" alt="Ferris the Rustacean") }}

Output

 
<img src="https://abridge.netlify.app/images/ferris.svg" alt="Ferris the Rustacean" width="600" height="400" loading="lazy" />

imgswap Shortcode

By default main_src is the image displayed, swap_src is displayed on mouse hover.

When you hover your mouse over the image it will display the image to compare.

main_src is the path and filename for the default image. (mandatory)
swap_src is the path and filename for the swap image. (mandatory)
class sets a class for the image. (optional)
alt sets the alt note for the image.
w is the width of the image.
h is the height of the image.

** google lighthouse recommends setting alt, w, and h attributes. If alt is omitted then the filename is used. If w or h are omitted then get_image_metadata() fills these values. **

Usage (same path)

{{ imgswap(main_src="ferris.svg" swap_src="ferris-happy.svg") }}

Output

<div class="img-swap-div"> 
  <img src="ferris.svg" class="img-main" alt="ferris" width="600" height="400" loading="lazy" /> 
  <img src="ferris-happy.svg" class="img-swap" alt="ferris" width="600" height="400" loading="lazy" />
</div>

Usage (relative path ./)

{{ imgswap(main_src="./img/ferris.svg" swap_src="./img/ferris-gesture.svg") }}

Output

<div class="img-swap-div"> 
  <img src="img/ferris.svg" class="img-main" alt="ferris" width="600" height="400" loading="lazy" />

</div>

Usage (root path /)

{{ imgswap(main_src="/images/ferris.svg" swap_src="/images/ferris-gesture.svg") }}

Output

<div class="img-swap-div"> 
  <img src="https://abridge.netlify.app/images/ferris.svg" class="img-main" alt="ferris" width="600" height="400" loading="lazy" />
