Accessible alt text translates an image's meaningful content into screen-reader-friendly prose, transcribes visible text, and focuses on what a post loses if the image disappears while avoiding filler. It ensures screen reader users grasp the image's actual point within platform length limits.
Alt text character limits vary by platform: X allows approximately 1,000 characters, LinkedIn around 120, Mastodon up to 1,500, and Bluesky roughly 2,000. Platform-aware generation adapts verbosity to fit these specific constraints.
Transcribing text inside memes and screenshots involves extracting on-image text such as labels, handles, and captions into screen-reader-friendly prose. The transcription captures visible text so screen reader users understand the visual context and meaning.
Automated image description tools can process charts and multi-panel images by translating their meaningful content into accessible prose. They transcribe chart labels and visible text, focusing on the core information conveyed by the visual elements.
When writing accessible image descriptions, avoid guessing identity attributes and inferring emotions. Distinguish observable details like facial expression and pose from subjective inferences to ensure accurate, respectful, and unbiased alt text generation.
Automated alt text generation for complex posts requires focusing on core meaningful content to fit platform character constraints. It avoids hedging and identity guessing, but may face limitations in fully capturing nuanced context if the image relies on highly implicit visual cues.
