Image styles

While we were reviewing the Teaser View mode, you probably noticed that the Featured Image is quite large. It would be nice if we could change the size of our image to be smaller, but how do we do that?

Drupal provides the ability to create image derivatives or image styles of any image uploaded and used for display. This feature provides us the option of selecting various image styles on the Manage display page. We can also configure additional image styles as needed.

If we tab back to the Manage display page, we can see that the Teaser display is currently using the Original image.

If we click on the Field Formatter for the Featured Image, we can configure our image to use one of the predefined image styles by selecting it from the drop-down list.

Choose the Medium (220x220) from Image style, select the Update button, and then the Save button. Now if we preview the Teaser View mode of our Post, we will see the new Image style being used.

Now that is a much better looking Teaser...

Chaz Chumley

Chaz Chumley

Chaz Chumley, ever since Chaz can remember, he has been picking up a crayon, a pencil, a pen, or a computer, whether to draw a picture, write a poem, share an article, or develop the next great website. Looking back at these qualities, it's the reason he chose to use those passions to give back to the open source community. His journey has opened doors to great experiences as a consultant, instructor, trainer, author, web developer, technical architect, Drupalist, and most importantly, a father. However, he could be none of these without first being a student and learning from life, love, and a passion for education, community development, and of course, science and technology. The sum of these things has allowed Chaz to share his experiences as an active member of the Drupal community, having participated in developing Drupal training videos, authoring multiple Drupal books for Packt Publishing, and giving back his knowledge by contributing numerous articles, training, and presentations at Design4Drupal, BadCamp, DrupalGovCon, and DrupalCon, all the while bringing topnotch Drupal expertise to his clients' work. However, his greatest journey is still in front of him as he continues to learn new creative ways to architect open source websites, write about the next best things, and laugh with his colleagues along the way.
