Icon sizes: 256x256, 128x128, 48x48, 32x32, 24x24, 16x16 File formats: ICO, GIF, PNG, BMP Why Do You Need to Use PNG Images in Your Website Creation?The benefits of including PNG images in website creation over various other formats ;for instance, GIF and JPEG; the file format helps to make good and wonderful icons that will wow your consumersThe PNG image format was introduced quite a while back; it was brought out in the market around 95/96 to cover the drawbacks of the the common GIF file format. However, it failed to create ripples because the then browsers were not designed to support the progressive attributes of PNG so website designers and creators were compelled to include it in their designs stingily. One of the main hindrances faced by the format was Microsoft Internet Explorer which was the most well known and widely used browsers of that period; IE had limited place for PNG support which equated to the fact that the format could only be made use of to a bare minimum. However, things changed with the introduction of IE7; this latest offering from Microsoft has aided in increasing the popularity of PNGs. So lets take a look at three reasons why PNG is one of the best image formats around today: You will be able to create see through images or alpha transparency: When you pitch GIF against PNG, you will see that a very distinct advantage with PNG is that you can only save a specific color as transparent in GIF this simply means that you can get the color whether opaque or transparent with just transparency in betweenbut when you use PNG, you get a serious advantage; because the format supports semi transparent pixels. With this attribute, you can save a PNG picture with a soft drop shadow and then use it against a background of your choice. The Image can also be used as a gradient background or water mark. The format gives you the option to use the slow fading of hues from fully opaque to transparent, and hence you will be able to view the webpage below They look spectacular: It is a well known fact that PNG images give you extreme flexibility also; there are a myriad of other advantages to using this format. For example, if you make use of the JPG Format, you lose a part of the data from the original file every time you save the file, so in time, you will be able to view a noticeable downgrade in the finesse of the pictures. Although, this problem has now been sorted in in the file type and you will be able to store the pictures without losing any data, GIF has a highly restrictive 256 color palette, which renders it quite futile if you are going to save a picture. On the other hand, with PNG, you can get the most desired attributes of the two file types; you get an extensive color display similar to JPEG images and it also provides managed color palette as seen in GIF files. Another advantage is that the compression of the picture is lossless so the photograph does not change even if you save the file several times. Self Optimization is possible in PNG: A major concern that web programmers face frequently is the fact that the contrast and the brightness of the monitor has to be regulated to see the pictures appropriately; this happens due to the difference in the Gamma setting used for the different monitors. Gamma setting is a technique incorporated to distribute the luminance across the display surface. However, diverse operating systems use distinct Gamma settings. So, multimedia that is color corrected to suit Windows will seem wrong when seen on Mac. Again, in this scenario the innovative PNG format can prove useful, in PNG, you can store the images with a built in Gamma correction so regardless of the operating system; the Gamma settings will be realigned to display a picture with the impressive brightness and contrast.
