Alt text: "Infographic: 5 steps to start home composting — collect food scraps, choose a bin, layer greens and browns, turn the pile, and harvest finished compost." Captures the data and sequence so non-visual readers get the same takeaway. Tip: place the full step-by-step text near the image too, since long infographics benefit from an in-body summary as well as alt text.

Alt text: "Sunrise over a mountain range with the headline 'Plan Your Next Adventure.'" Because the headline text is part of the image, include it so screen-reader users hear the call to action. If the same headline already appears as real HTML text nearby, mark the image decorative (alt="") instead to avoid duplication. Keep it under ~125 characters.
