What should you most consider when deciding whether an image is appropriate for your technical document?

When deciding if an image is appropriate for a technical document, consider its relevance to the content, ensuring it enhances understanding rather than distracts from the message. Evaluate the clarity and quality of the image, as it should be easy to interpret and professional in appearance. Additionally, ensure that the image adheres to copyright and licensing regulations, and that it aligns with the document's tone and audience expectations.
