Best suitable image format for website.

PNGs are designed to be a more efficient, flexible, and patent-free replacement for GIFs. By replacing your GIFs with PNGs you can speed up your web pages and save bandwidth.













ImageRanking according to Browser Compatability or Popularity
JPEG: Size: 1451 bytes Or 1.41 KB
Transparency Support: No transparency


Jpeg image is best option if we need to show photographs like in photoalbum
or showing prtoduct images and so on. But for graphical images like cartoons
and illustration images, jpeg is not a good option.
GIF: Size: 2168 bytes Or 2.11 KB
Transparency Support: No transparency


As we can see it is quite heavier then jpeg image. So it is not a good
choice for web images. PNG-8 Bit without transparent image is the best
alternative option of Gif image. But it is useful if we want to show some
animation, gif will be the right option. Gif support animations. And Its
weight(KB) will be depends on its Animation.
GIF: Size: 2168 bytes Or 2.11 KB
Transparency Support: Binary Transparency


As we can see, there is no difference between both GIF images. both have
same size(Width and Height), same weight(KB) except transparency effect.
So we have both options according to need.


Suppose we need to show background then we can go with transparent GIF
image. But if we have a transparnecy issue we should go with PNG-8 transparent
image. because Both(GIF and PNG-8) have binary transparency but PNG-8
is lighter then GIF. PNG-8 bit takes lesser time to load on webpages.
PNG-8: Size: 1387 bytes Or 1.35 KB
Transparency Support: No Transparency


It is best alternative options of JPEG and GIF image formats. Comparatively
lighter then other non transparent image formats. It is compatiable with
all browsers. It represents better graphics then other GIF and Jpeg(Except
photographs).
PNG-8: Size: 1571 bytes Or 1.53 KB
Transparency Support:Binary Transparency


Best suitable image format for web applications. With transparancy and
light weight features. Contains better graphics. compatible in all browsers.
PNG-24: Size:1689 bytes Or 1.64 KB
Transparency Support:No Transparency
PNG-24: Size:2127 bytes Or 2.07 KB
Transparency Support:Binary and Alpha channel Transparency


It supports Both type of transparency(Binary and Alpha Channel). But
Alpha channel transparency is not supported by IE 6 and Its lower version
browsers. Thats why it is not a good choice. even it is heavier then PNG-8
bit and Lighter then GIF transparent.


SIZE ( KB) Comparision : PNG-8 < PNG-24 < GIF


Conclusion:-


PNG-8 Bit is the best suitable image format for
website.


JPEG is the best suitable format for photographic
images.

Leap Year Calculator

Image
We know any year that is evenly divisible by 4 is a leap year : for example, 1988, 1992, and 1996 are leap years.  However, there is still a small error that must be accounted for. To eliminate this error, the Gregorian calendar stipulates that a year that is evenly divisible by 100 (for example, 1900) is a leap year only if it is also evenly divisible by 400.  For this reason, the following years are not leap years: 1700, 1800, 1900, 2100, 2200, 2300, 2500, 2600 This is because they are evenly divisible by 100 but not by 400.  The following years are leap years: 1600, 2000, 2400 This is because they are evenly divisible by both 100 and 400.  How to determine whether a year is a leap year To determine whether a year is a leap year, follow these steps: If the year is evenly divisible by 4, go to step 2. Otherwise, go to step 5. If the year is evenly divisible by 100, go to step 3. Otherwise, go to step 4. If the year is evenly divisible by 400, go to step 4. Ot
