| Besides small files, photo optimization in web design is highly essential for quick web page loading. In an ideal case, web designers might use high quality photos, allowing web pages to download lighting fast.Online sites usually save a fixed space for small size file pictures. Unfortunately, there remains a trade off between file size and picture quality, which affects the load timing. This turns potential visitors away, never to return back.Many web design computer systems display images at 72 dpi and hence, the first step towards photo optimization lies in decreasing the screen resolution. Large pictures are usually sliced up into smaller ones for use on web pages.Each piece contains small files which load together at a fraction of the single image load file. Besides, many graphic programs discard unnecessary file information without affecting picture quality.Different ApproachAnother web design method which speeds up the load time is the PNG or GIF with progressive inter placement. These properties allow the gradual loading of picture, initially as a blurry image and thereafter yielding clear and sharper pictures.Many graphic files contain information on the color palette of the image, which, usually are unnecessary to display on the web. They also contain additional web saving facility and discard unwanted information without loss of picture quality.Third MethodologyYet another method to speed up the load time is by either using the interlaced version of PNG or GIF or by using JPEG property. They assist in gradual loading of picture, initially as blurry image, which later becomes clearer and sharper.Many graphic files contain important information on the image's color palette. They are usually important for web display. Many graphic programs include the save for web ability, which discard all unnecessary file information without affecting the quality of images.
