Everything can be perfectly optimized in a good Drupal expert’s hands! See how Drupal can solve all the above mentioned issues with the help of image styles. What to do? Well, it’s pretty bothersome to trim each image, especially if you have plenty of them to upload. In addition, right image formatting is crucial for your website performance. This is neither attractive nor convenient. Image sizes are worth a separate discussion, but huge wallpaper images may come alongside with small thumbnails create a “chaos” on your site’s pages. These can be in PNG, JPEG, or GIF format. How website images are usually uploadedĭo you sometimes or regularly upload images to your website or allow other users do it? Then images probably “arrive” in different sizes and formats. Let’s start discovering more details.īut before we delve into Drupal image styles, we first need to take a glimpse at website image uploading practices. This Drupal’s treasure is called image styles. It can raise a website’s attractiveness and usability, create consistency in its looks, increase its performance due to image optimization, and significantly save its owner’s efforts and budget. When we say one tool, it’s hard to believe how many things it can do. In the next part of this tutorial, we’ll look at using the Manual Crop module in order to give that control back to content editors.Drupal has many built-in tools with truly magic powers, and today we will describe one of them. The only downside to this is Drupal is deciding what the focal point of the image is, which may not always be desirable. If you create a piece of content, the rendered image should get switched out if you view the full node and resize the window. This is what image will be used in browsers that do not support media queries. One important thing to notice is the Fallback Image Style. Visit the Manage Display tab for a content type with an image field, and set the Format to the Picture Mapping we set up. Once all this has been set up, we can now use our Picture Mapping as a field formatter for an image field on the site. In our case we want to match each breakpoint up to the appropriate image style we created earlier. Enable the Picture module and add a new Picture Mapping (admin/config/media/picture).Īfter you’ve chosen your Breakpoint Group, you’ll have some options as to what should happen at each breakpoint. While the Breakpoints module handles the definition and organization of breakpoints, the Picture module uses Breakpoint Groups to create the markup. With Breakpoint Groups, you have that ability. Imagine you have several more breakpoints defined, but you want to pick specific ones to apply to one component of the site. Next you need to create a Breakpoint Group (admin/config/media/breakpoints/groups/add). We’ll use the interface (admin/config/media/breakpoints) to create three breakpoints. The Breakpoints module has two ways to define breakpoints, in the interface or in your site theme’s. Install Breakpoints and its dependency, CTools. There should be an image style for each, and for now it should have a Scale and Crop effect set to our dimensions.ĭrupal needs to be made aware of the breakpoints our site uses, and the Breakpoints module does just that. We have three contexts to plan for small, medium, and large displays. Setting up the image stackįirst we need to create the image styles for our breakpoints. In part 2 we’ll look at opening up control over the art direction of the images, while still maintaining the design’s layout rules. Using Drupal, we can automate the creation of the needed versions of a single image, making content creation that much easier. HTML5’s ‘picture’ element addresses these challenges, and so many more. Or you may want to serve the same image, cropped differently to work better with layout changes at different breakpoints. You may want a scaled-up image to optimize for high resolution devices. You may want to serve up a scaled-down image in an effort to optimize performance. In our current world of changing screen sizes, screen resolutions, and bandwidth the effective use of imagery has not only become more important, but a lot more challenging. Solid imagery can make or break a design. ![]()
