Image File Formats
There are a number of image file formats that have been used and that are still being used to save pictures on a computer, bmp, eps, gif, iff, jpeg, pcx, raw and tiff to name a few. There are usually compromises to be made on what type of image format you use. For the web the jpeg format has become the most popular offering a choice of compression as to the amount of detail you wish to preserve or remove from your image.
Where the utmost detail is required than no compression must be allowed an example of this would be an x-ray of a patients broken ankle, detail here that is lost in compression could produce the wrong diagnosis. The more the detail that is required in an image the bigger the file size.
In the future when high network speeds become available to everyone this problem of file size will not be an obstacle to how much an image is to be compressed. Perhaps in the future there will be no compression as computers and associated hardware become far more powerful than they are today. Coming back to today however and viewing large images on a dial-up connection is a very slow process. Image file size is a problem especially if you are on a dial-up connection which surprisingly there are a great number of people still using this form of connection. Below is a list of some of the once and still popular image formats in use and a description of how they work.
Jpeg compression provides an efficient way to reduce the file size of an image. One of the benefits of this is the reduced download time of the pictures.
Depending on compression settings when the picture is saved a greater or lesser amount of detail will be in the image. Image file size is therefore a compromise especially on the internet.
free jpeg images why not use them for calendars, desktop pictures, background images and if you are studying then why not add them to your work!
