When choosing images, it's important to use high-quality images that are clear, sharp, and appropriate for your format and platform. Doing so can enhance your credibility, readability, and professionalism. On the other hand, low-quality images can damage your reputation, distract your readers, and reduce your impact. To ensure you use high-quality images, consider factors such as size (large enough to be seen and understood but not too large to slow down loading time or overwhelm text), resolution (enough pixels to be displayed clearly on different devices and screens but not too many to consume too much bandwidth or storage space), format (JPEG, PNG, GIF, or SVG; avoid formats like BMP, TIFF, or PSD that are outdated or unsupported), and source (ensure you have the right to use the image either because you own it or have permission from the owner or a license from a reputable source; avoid images that are copyrighted, trademarked, or otherwise protected without proper attribution or consent).
