Amit from Labnol says creation of image sitemap is very important due to the following reason:

Now a days the number of sites are increasing and the total number of the pages on a specific topic is generally very high. In order to distinguish yourself from others you have to increase the readability of the site, which can be achieved by proper usage of the images. Now the problem starts, if you are ready to put enough number of images in the webpage to make it look more better, then google may not distinguish which one among them all is more relevant to the topic to display in the google image search. This may probably lead to the reduction of number of hits your age gets.

So in order to make it work with google images, you need to have a proper sitemap for the images in your website.

Now How to create an image sitemap for your site?

For WordPress users: You can create an image sitemap for your wordpress site by using the XML sitemaps plugin.

Now the question is..

Is it worth having the image sitemap?

If this is the question, the answer is NO. It is not worth having the sitemap for images. The sitemap amit developed is complained to be buggy and not worth to have it.

Secondly, google can crawl and index all the images that is reletively important while crawling the page that is having images. So unless you are developig a very big site, it is not worth having the Image sitemap plugin.

When you decide to shift from your blog from your current host there can be several reasons to move your blog to another host. Primarily, the most common reason for this transfer is the unreliable service of the original host, where downloading could take as much as several minutes in a day.

1. Backup the database: Firstly, upgrade your WordPress installation including, files and databases on the WordPress blog. This will help you to have a backup all your uploaded files, images, plug-ins and theme files so that it matches the script version of the new host. WordPress database backup plug-in will be able to help you achieve this task in a snap.
2. Backup the Wp-Content folder: This task can be completed by using FileZilla or any other FTP program. Wp-Content folder is pretty important as it holds your plug-ins, themes and all the uploads (files & images).
3. Install WordPress on your new host: Most of the hosts will provide you an IP address through which you will be able to manage your web host account and will be able to make the changes on it.
4. Delete the old tables: Delete all the tables which were created with your new installation of WordPress.
5. Import the old database: With the help of phpMyAdmin or SQLyog community edition you will be able to import the old database completely.
6. Replace the Wp-Content folder: Replace the wp-content folder which got created with the new installation and approach the new host technical support for more memory space.
7. Customize the new wordpress installation: This is done by editing the required database information found in the file of the root folder of the installation wp-config.php. This has to be done according to the name of the imported database, your user name, password and the host name, which is usually local host.
8. Change the name servers: Change the name server with the help of your domain registrar control panel, you have to change the name server of your existing domain to the name server of your new hosting company and in the next 24 hours your blog will work just like normal.

Quick Tip: If you use Google Apps for email solution for your domain, then don’t forget to change the MX server details too and avoid loosing a lot of important e-mails.

The resizing of width and height attributes on images ensures fast webpage display and conserves bandwidth. Most bloggers use images to spice up their look. I am having an issue with the new image caption feature in Word Press blog. Apparently, it is automatically adding 10px to the width of the caption surrounding the image. Similarly, you may be encountering the same issue with Image Width while using Word Press blog.

The resizing image width is essential when you are adding multiple images to your blog. The default wordpress theme automatically resizes the image to the themes maximum width. But there are always problems while using this wordpress plug-in and there are no immediate solutions as they are coded. The max width attribute is still hard coded. I mainly use 500px wide images, but every now and again I need to post a smaller width image, say like the sausage dog, I can’t really used fixed width divisions because I can’t accommodate for all images.

How Image Width Resizing is possible in Auto Mode?

You need to access your (Sample Style Sheet) style.css that is located in the wordpress theme folder and add the following code:

post img {
max-width: 530px;
width: expression(this.width > 530 ? 530: true);

}

Let us assume that an image posted in your blog was of the size 800px × 130px but it got automatically scaled down to 530px × 120px , which means that it resizes the images to the given width and height respectively. You must find the maximum width of the content part of your blog and save the dimensions in the above given code. Once saved, it starts working and resizes all the images to the given width or size dimensions. With an external style sheet (css), you can change the look of the entire site by changing one file. The custom options include colors for all layout sections. Definitely, your blog can look quite different than someone else’s.

Image Alignment

You can remove the option to float all images left or right site-wide. Instead use the WordPress editors align left or right feature when inserting an image that you want to align left or right as it is less troublesome.
