Blog image idea

The design team will work on a design for the blog image. Add any ideas you have about the graphic image here.

Prerequisites

• The draft is complete and this post is ready to be reviewed.
• I'm familiar with the guide for blog content basics.
• I've checked the content using Grammarly and the Hemingway app to remove typos, grammatical errors, and passive voice.
• The PR build passes validation, and if it doesn't, I've checked the common validations errors and none of those apply.
• The images I've included follow the rules for working with images.
• I've added alt text for all the images I've included (alt text describes image to people unable to see it, 125 characters max)
• One screenshot (if any are included) is suitable for Twitter. This screenshot should be 16:9 ratio and at least 1200 x 675 pixels. For screenshots from the Octopus Web Portal, please use Chrome and the browser’s zoom function to remove as much white space as possible. If screenshots are annotated (e.g., with boxes or arrows), please also provide a version that is unannotated for use on Twitter. Do not use dark mode for the Octopus Web Portal.
• I've drafted social media posts for Twitter and LinkedIn.
• I've dropped a note in Slack in #topic-content-marketing to let Tegan Ali know my post is ready for review.
