Sliced imaged and Speeding up the page loading

S

Svetlana

What is the best way to upload sliced image on a page?
For now I am doing it manually - copy - paste.

How to speed up page loading? Especially when there are
tons of images, graphic on it?

1. If the images have been imported into your web, then they will be
published when you publish the web.

2. To speed up page loading, optimize your image and reduce the number being
displayed on each page.

Slicing images doesn't speed page loading, actually it
will slow it down, as extra code is needed to reassemble the images.

It does however, make it "Appear" to load faster because people
get to see something while they are waiting.

To speed page load, resize / resample your images
to the actual size you want to display on the page.
If you don't have an image editor get a copy of the free
IrfanView. It is quite versatile.

Also, validate your html, as invalid html forces the browser
to parse the errors and this will slow down the browser.
You can do this with a free utility named
CSE Lite html validator. Hint: when using it start at the top of the
page and correct one error at a time ( if there are any ) save and
reload and recheck. Correcting one error will often correct others.

I believe there is one minor correction: By my understanding, sliced images
will speed up download times to an extent.

Four packets can cross the wire at a time, so with the following example:

connection speed: 100K/second

If you have an image that is 100k, that passes over the wire all by itself
in 1 second.

BUT

if you have four images that are 25k each (like slicing the 100k image up
into four parts) the image will download in .25 seconds because all four
images can cross the wire at the same time.

if you have four images that are 25k each (like slicing

download in .25 seconds because all four images can cross
the wire at the same time.

Suppose you have a 50kbps modem connection. Accounting for
overhead, it will transmit about 5 kilobytes per second,
so a 100KB picture will take 20 seconds to download.

Now, split the picture into four. With all four
connections open, each one will get about 25% of the
bandwidth - 1.25 kilobytes per second. So each of the four
segments will take 25/1.25 = 20 second to download.

However, it does take time to open and close the four
connections. So downloading the picture in four segments
may actually take a little longer.

And don't forget, while that single 100KB picture is
downloading, other pictures on the same page can use the
other channels.

OK, I admit, when downloading a large file, there are time
gaps when the line is idle, and performing multiple
downloads at the same time may keep the line a little
busier. But this isn't a large factor.

Downloading many small files just isn't reliably faster
than downloading the same number of bytes in one large
file. The only change that makes a big difference is
decreasing the total download bytes for the entire page.

Providing:
1. that the bandwidth is not "capped" and thereby divided
between the 4 ports.
2. That the server is configured to allow multiple
port 80 connections. Not all are.
3. That the client machines "ports per session" is set to allow
multiple ports. It's regulated by a registry setting.
4 is max for dial up.
Broadband can be as high as 40, providing that the
server will allow it.

There are freeware programs around that you can use to slice your images, and the
added bonus is they generate your HTML Code (table) and reassemble the image for
you. It is then a matter of cut and paste.

Try Tucows.com for software.

If you want commercial products, Macromedia Fireworks and Adobe Photoshop offer
the similar features.
