Images of Text
Images of text refers to readable text that is uploaded as an image.
The Web Content Accessibility Guidelines (WCAG) recommend avoiding using images of text if you expect the text to be read by the user.
All information that is needed for visitors to read should be text on a page. Genuine text is much more flexible than images: It can be resized without losing clarity, and background and text colors can be modified to suit the reading preferences of users. Images are more likely to distort and pixelate when resized. In those rare situations where images of text must be used, the text alternative must contain the same text presented in the image.
Images that Convey Simple Information
An image of text such as a logo is not accessible without appropriate alternative text. The text alternative must contain the same text presented in the image.
Images that Convey Complex Information
The image text that contains more than 15 words is not accessible because it contains too much embedded text. Complex images, such as graphs, charts, or diagrams, may contain too much information to be effectively described using alt text. Instead, these images must be described with text on the page and / or an image caption. Long description is a more detailed description that provides equivalent access to the information the image. The best choice is to create the text as text on the page.
