Here is the answer for this questions.
The important reason for this fact is due to the high graphical contents and unproper alignment for the page elements like widget and banners etc. So if the site is not properly planned and not maintained without an webmasters methods. Your sites or blogs will also be behaving the similarly.
I knew that not every one can get the webmasters help, So i have posted this stuff in order to help and guide other bloggers facing this problem in" webpage takes long time to load".
So don't worry about this problem here i will give you some important and best idea to resolve this problem on your sites as well as your blogs.
Have you seen some picture takes long time to view, this is only because it is well defined an size of the image is also large. So simultaneously the loading of the picture take very long time to download an to be viewed. So when these types of images are posted or added to your site the same problem in loading appear on your site too.
You should check the different image formats i mean .jpeg, . Tif, .Png,..etc.
GIF vs JPG vs PNG
Personally on new sites I design I tend to go for optimized pngs. They have lossless compression (unlike jpgs and can be used without worry (gifs have the potential to have copyright issues) and load fast! With all that said, if you still want to use gifs and jpgs, here's a bit of fast info... If you don't need sharp resolution, choose GIFs over JPEGs, as GIFs generally load quicker. JPGs are generally best for photos, GIFs for anything else.
(I'd add a rant here about how Microsoft had held up the web's development with not making IE6 support png transparency... but *sigh* I've ranted about this already to anyone who will listen. Firefox, Opera and other modern browsers however have been able to show alpha transparency in png for years... oops, sorry, that was a mini rant after all!)
Faster Images? Reduce Their File Size
There are many totally free, online image optimizers so you don't even have to install anything and it's extremely easy! Online Image Optimizer will greatly reduce the file size of your gif, jpg, or pngs and neither you or your visitors will be able to see the difference other than a page that loads a heck of a lot faster. They also keep the transparency and animations in gifs! For another JPEG reduction, try JPEG Wizard, also free, this one will only work with pictures in your hard drive not ones from the net. You can also choose some simple effects to be done (flip, mirror and rotate).
Remove Excess "Whitespace"
Whitespace is the spaces between your coding, removing the unneeded tabs and spaces can help a lot! Doing this will take a lot of extra bytes off the total size of your page and will speed up load time quite a bit. (Careful using automatic squishers, I find they often squish too much and makes it rather hard to edit later.)
Use CSS For Faster Pages
Even if you decide to use tables, CSS can greatly improve your web sites load time! With your styles in an external .css file, the browser can cache all the formatting and stylizing for your pages instead of having to read each and every single tag all over again. Also it cuts down on long drawn out tags and replaces them with smaller class styles instead.
That way the browser already has it in it's cache and won't have to read it each time another page loads. This one saves a ton of load time, specially for larger scripts!
Remove Anything You Don't Really Need
OK, while this might sound obvious sometimes the hardest thing about creating a website is not using every fancy trick that you know. Images, flash and sometimes even sound files are very impressive.. but do you really need to showcase all your talents on one page?
Embedded sound files are something many people just find annoying anyway. You'd be surprised how many are surfing at work ;-). The last thing anyone wants is a loud music or sounds announcing to their boss that they're surfing. Also many people have their own music playing... hearing a song over top of what we're listening to is less than pleasant. As for Java applets, try to ditch them or if you want those effects, JavaScript unusually loads faster and can do just as much or more. Stand back and take a critical look at your website, you may see a few special effects that can be let go of for the sake of faster load time.
