Adam W. Warner answers:

Why not go to Settings-->Media and set the size you want for one of the default sizes? Read here for further explanation:

Hi,

You can use Tim thumb. http://www.binarymoon.co.uk/2010/08/timthumb/

here is the script http://timthumb.googlecode.com/svn/trunk/timthumb.php

After you have uploaded the script, use the following html to auto resize the image.

HTML example:


<img src="http://example.com/scripts/timthumb.php?src=/images/whatever.jpg&w=150&h=200&zc=1" alt="" />


This script was originally written by Darren Hoyt, one of the owner of WP Questions.

Thanks.

If you're using WP 3.0 there are a couple of ways you can accomplish what you'd like to do.

First of all, you can set your default image sizes in Settings->Media

If you need more image size options, you can create as many as you'd like by adding a few lines to your themes functions.php file.

add_image_size('Slideshow', 500, 260, TRUE);
add_image_size('Mini', 90, 90, TRUE);

These can be adjusted to your needs and then called from within your theme using the following code:

the_post_thumbnail('Slideshow'); // will display the 500x260 image
the_post_thumbnail('Mini'); // will display the 90x90 image

Finally, if you already have a lot of posts with images, once you've added the code above, you can use the Regenerate Thumbnails plugin: http://wordpress.org/extend/plugins/regenerate-thumbnails/

I would recommend installing the nextGen Gallery plug-in. It is in my opinion the only way to handle images using Wordpress. You can set it to resize images at upload, set thumbnail sizes, organize images by gallery or insert single images inside of the text editor. NextGen gallery also has several add-ons which can be found at the plug-in download page.

First, you need to make sure that post thumbnail support is enabled for your theme;

In the functions.php file;
=============================

add_theme_support( 'post-thumbnails' );

//Then set your sizes

set_post_thumbnail_size(150,100,true); // or whatever size for small default images
add_image_size('large-thumb',1024,800,true);

==============================

Then to call it within the loop;

if (has_post_thumbnail){
the_post_thumbnail('large-thumb');
}

===============================

Use the featured image utility in your posts to upload new images.

David answers:

I would go with the previous answers by Duncan O'Neill on setting your image sizes

and then If I understand your question correctly this plugin will help to resize all existing images to the sizes that you setup
