Technical reasons for not having large background images in websites


Technical reasons for not having large background images in websites

With these it helps You've pretty much identified the two main reasons, but the most important one is bandwidth. Depending on the type of image, you'd be best to consider all those users in your target audience whose technical limitations mean that sitting and waiting on a dial-up connection (they're still out there, you know) will alienate them.
In addition to the time and resource cost of sending large images down the pipe to your users, the usability issues of forcing the user to wait for the image to load and the impact of readability of content mean that background images should best be limited to tileable, scalable or small UI enhancements rather than full UI features.

Hope that helps Update 2015:
In this answer from 2011 I'm talking about libraries like jQuery, YUI or Prototype. Today in 2015 that reasoning is still applicable to frameworks like Angular, React or Ember. In those 4 years the technology progressed tremendously and even though I see considerably less prejudice against React or Angular than I saw against jQuery or YUI, the same kind of thinking - though to a lesser extent - is still present today.

The Java compiler (javac) does not compile all the classes at the same time, but rather one by one, dynamically discovering uncompiled or stale .class files.

I wish this help you I'm using simple_html_dom.php to get all images from an url (like pinterest does) , You may use CURL library:
code :
$url =  $_POST['form_url'];

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url); // set url to post to
curl_setopt($ch, CURLOPT_FAILONERROR, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);// allow redirects
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); // return into a variable
curl_setopt($ch, CURLOPT_TIMEOUT, 7); 
$resultHtml = curl_exec($ch); // run the whole process
curl_close($ch);

$html = new simple_html_dom();
$html->load($resultHtml);

To fix this issue The problem is just about extracting the link to the large image from HTML source of the page. If you view the HTML source of http://www.firebox.com/product/5773/Scientific-Spice-Rack?via=hp&s=1x1&t=random you can actually see the links to big images, see part of HTML below:
code :
<img class="extra_thumb" data-item="0"   data-sku="sku14014"  data-zoom-image="http://media.firebox.com/pic/p5773_column_grid_12.jpg" data-caption="" data-image="http://media.firebox.com/pic/p5773_column_grid_6.jpg"  src="http://media.firebox.com/pic/p5773_column_grid_1.jpg"/>
#!/usr/bin/perl                                                                                                                                                                                                                                                               
use strict;
use warnings;
use LWP::Simple;
use feature 'say';
use List::MoreUtils qw( uniq );

my $content = get('http://www.firebox.com/product/5773/Scientific-Spice-Rack?via=hp&s=1x1&t=random');
die "Couldn't get it!" unless defined $content;

my (@big_images) = $content =~ /data-zoom-image\=\"([^\"]+?)\"/g;
say for uniq @big_images;

will help you Javascript files are often combined in production environments to cut down on server requests and HTTP overhead. Each time you request a resource, it takes a round trip from the client to the server, which affects page load speed.
Each separate request incurs HTTP overhead, basically extra data that is attached to the request/response headers, that must get downloaded too.Some of this will change with the implementation of HTTP2, and smaller files will become more efficient.
