$_POST['user_login'] is then sanitised and processed as if it were a username.

function make_username_email() {
$_POST['user_login'] = $_POST['user_email'];
}

add_action( ‘login_form_register’ ,’make_username_email’ );

If you create a featured image (using post_thumbnail), you can set the exact dimensions of the image so you won’t need to scale the image size down.

E.g: add_image_size( ‘slider-image’, 200, 200, true ); will create a featured image 200px x 200px in size so you can fit it exactly into your slider.

Hope that helps.

I also need to know how to make it scaled (add thumbnail size on slider image in preferred dimension)…so the pagespeed.googlelabs won’t show that advice…”serve scaled images”

thanks

Thank you very much for this tutorial.

I came with idea that it would be better to generate usernames from random numbers than letters.

When users go to their profile pages and they will see that their login consists of random letters they might think that it is some kind of error in the system.

But if they see random numbers they will not be so confused about this – we are numbers in this world, so it’s easier to understand that my user name is just some numbers.

Second thing is that in WordPress 3.1 i can’t find user name input field in wp-register.php

How could i do it here?

<input type="text" class="text" tabindex="2" name="your_email" id="your_email" value="” />

<input type="hidden" class="text" tabindex="1" name="your_username" id="your_username" value="” />
