There are a few image file formats that allow you to create basic frame-by-frame animations. One of the best known is the GIF89a format (see below). Here is a list of common image file formats:

  • BMP bitmaps: large files not easy to compress;
  • GIF: small file size of 256 Kb; ideal for web buttons and banners;
  • GIF89a: small file size, but allows for transparency of certain colours and animated images;
  • JPEG: higher quality good compression, ideal for pictures;
  • TIF: large file size, high quality;
  • PNG: like gif, but slightly better yet still not fully supported by Internet Explorer.
