"ALT" is the abbreviation for alternative text, which is the technical name for image description. The ALT badge on images lets you know when someone has added a description to their image.
To read the image description:
- Select the ALT badge and the image description will appear.
The GIF label is not interactive like the ALT badge. The GIF label communicates that the media is a GIF and has movement. For those who choose to have media auto-play turned off in their timeline, it's helpful to have the GIF label to differentiate from static images.
If a GIF has an image description, the ALT badge will appear next to it, and you can select it to read the GIF description.
