  "account": "When designing and testing small, transparent images like icons and emotes, it's crucial to ensure they appear crisp and clear across various platforms and backgrounds. Begin by keeping the original artwork separate from the exported version to prevent unintentional resizing. Export a PNG with a clear, descriptive filename, such as wave-32.png, and verify the platform's size and file restrictions beforehand.\n\nTo check the exported asset, display it against contrasting backgrounds, including white, dark, and mid-tone colors. This will help you spot any unwanted halos, opaque areas, or lost details in the small images. You can use a simple HTML page with a light, dark, and mid-toned background divs to facilitate this comparison. Be sure to replace the sample filenames and descriptions with your own assets.\n\nWhen reviewing the image, double-check its pixel dimensions, ensuring they match the intended display size. If the image conveys information, provide an appropriate alt text. If it's merely decorative, an empty alt attribute may be sufficient. For an emote picker, ensure the control has a clear name and is accessible via keyboard.\n\nPrepare a review sheet to compare different versions side-by-side. This helps reviewers quickly spot discrepancies. Label each variant and keep a backup of the original file. Tools like Free Image Merger can assist in combining images for easier review. Before utilizing any such service, review its privacy policy and avoid uploading sensitive artwork unless you're comfortable with their handling.\n\nLastly, perform a final pass comparing each export with the source image, ensuring there's no unwanted cropping. Test the smallest intended size against both light and dark backgrounds, and confirm dimensions, transparency, filenames, and any platform-specific limits. Always retain the original files so you can make revisions without degrading the quality of your small exports. The aim is to establish a consistent visual check process, rather than guaranteeing full platform compatibility.",
  "summary": "Small icons and emotes often look fine in a design file but lose detail on a busy page. A useful test is to review the exported asset at its final display size, on both light and dark surfaces, before sharing it. This checklist works with any image editor and a modern browser. 1.
