Unlocking the Hidden Power of Images in Your Documents
When you create a PDF, Word document, or presentation, you likely spend time choosing the perfect images.
But here’s the big question: Are your images accessible to everyone?
If someone couldn’t see your document, would they still understand it?
If not — don’t worry. Today, you’ll learn the simple steps to make every image count.
Why Images Matter More Than You Think
Images aren’t just decoration. They can:
- Explain complex processes
- Show real places and people
- Visualize important data
- Help guide navigation
When images aren’t properly described, a huge part of your content becomes invisible to people using screen readers or other assistive technology.
Meet WCAG — In Plain English
WCAG stands for Web Content Accessibility Guidelines.
Think of it like a recipe book that shows how to make websites, apps, and documents usable for everyone — including people with disabilities.
One important part of WCAG is called Non-Text Content.
It simply says:
Every meaningful image must have a text alternative that explains what the image shows.
That’s it. Simple, right?
The Secret Recipe for Writing Great Alt Text
Here’s your easy-to-follow checklist:
Step 1: Ask yourself — what would someone miss if they couldn’t see this?
Step 2: Describe the essential information briefly and clearly.
Step 3: Match the description to the type of image:
|
Image Type |
What Alt Text Should Cover |
|
Photo |
Describe what’s happening or who is pictured. |
|
Diagram |
Explain the key process or relationship shown. |
|
Chart or Graph |
Summarize the main data trends or message. |
|
Map |
State the purpose of the map and key locations. |
Step 4: Skip decorative images.
If the image adds no useful information, you can simply mark it as decorative.
Step 5: Keep it human.
Write naturally, like you’re describing the image to a friend.
Quick Tip to Remember
Every time you insert an image, pause and think:
If someone can’t see this, what do they need to know?
This tiny moment of reflection can make your document truly inclusive.
