Magento - Can't login to admin in localhost

I am currently working on magento version 1.3.2.4. When i login to admin, it looks like i have entered proper username and password because it doesn't show any error like "Invalid username or password". When i try with fake login I do get error. Even i am not getting any error it stays on the login page.

So, I had to go through code and comment out few lines after which I was able to login and access admin again.
app\code\core\Mage\Core\Model\Session\Abstract\Varien.php line 77: original:

// set session cookie params

session_set_cookie_params(

$this->getCookie()->getLifetime(),

$this->getCookie()->getPath(),

$this->getCookie()->getDomain(),

$this->getCookie()->isSecure(),

$this->getCookie()->getHttponly()

);

Commented out three lines:

// set session cookie params

session_set_cookie_params(

    $this->getCookie()->getLifetime(),

    $this->getCookie()->getPath() /*,

    $this->getCookie()->getDomain(),

    $this->getCookie()->isSecure(),

    $this->getCookie()->getHttponly()*/

);

First go to Template > Edit HTML
In Blogger default templates, search for <body> and in custom templates, search for <body>
Add the below code just after above code.

<b:if cond='data:blog.pageType == &quot;index&quot;'>
<b:if cond='data:blog.searchLabel'>
<style>
.status-msg-wrap{display:none;}
</style>
</b:if>
</b:if>

Now Save the template and check the result by clicking any of your labels

Auto-Resize WordPress Featured Image and Crop if Necessary

If you are creating a WordPress site for a user, you want to make sure everything is as easy as possible for them. One trick that can make things easier is to have images automatically resize when they are used for a featured image in WordPress. Resizing images may be easy for developers and graphic designers, but some end-users don’t have the skills or time to resize an image to fit perfectly in your design. Luckily, this is simple to set up.

Steps

Before we even start, make sure that your theme supports thumbnails. To do this just make sure the the following line of code is in your functions.php file.

add_theme_support( 'post-thumbnails' );

The next step is to put the following line of code in the WordPress theme’s functions.php file.

add_image_size($name, $width, $height, $cropBoolean);

The add_image_size(); function has 4 parameters. $name is the name that you want to call your image with. $width is the width you want the image to crop to in pixels. $height is the height you want the image to crop to in pixels. $cropBoolean is a true or false parameter. If set to true the image will crop itself automatically.
In the example below, the name I use to call the cropped image is “featuredImageCropped”. The height and width are 250px and 200px respectively, and the image is set to crop.

add_image_size('featuredImageCropped', 250, 200, true);

The next step is to reference the new image size in your theme. Place the following code wherever you would like to see your cropped image:

<?php the_post_thumbnail('featuredImageCropped'); ?>
