Write alternative text and captions for the images in my PowerPoint deck. For each image I give a description and the purpose of the slide: [IMAGE_LIST]. Audience: [AUDIENCE].

Treat each image separately and say what job it does on the slide: show evidence, illustrate a point, set a mood or decorate. Classify it as informative, chart, diagram or decorative. Alt text serves that job: one or two sentences conveying what matters, under 125 characters where possible; for charts, state the type, the trend or comparison and the key numbers from my description, with a longer description in the notes or a text box if the chart is complex. Decorative images should be marked decorative and given no alt text. Example: a photo of a team at a whiteboard is informative, alt text 'Three colleagues sketching a process on a whiteboard'. Point out any image whose meaning depends on colour.

Provide visible captions and credit lines in a consistent pattern where the source is known. Do not invent details I did not describe; mark gaps [DESCRIBE]. Return a table by slide.

Optional: type your details and the prompt above updates. Nothing is saved or sent.
