Bitmaps are memory hungry. In some cases a 700k picture in bmp will be 125 in jpeg and smaller in other formats. Remember, as a webpage downloads it tries to leave picture info in a temp file for reuse and to save the whole thing having to come down again. That is why to optimise the download speed smaller efficient picture formats are used.

What does bitmap mean Bitmap?

Vector and bitmap are both image files. Bitmapped images are images that are stored on a pixel by pixel basis and because of this, when you enlarge the image it can appear blocky. A vector image is constructed from dots, lines, shapes, etc. Each part has a particular position within the image with it's own dimensions. Because vector images are constructed using images, they can be enlarged without loss of image quality. Vector images do not get the blocky appearance of an enlarged bitmap image.
