Is it necessary to use Timthumb in Wordpress 2.9+ ?

I’m pretty sure that WP thumbnails can be resized to anything if you setup multiple dimensions in functions.php. A downside to this is that you will have multiple versions of your images taking up unnecessary space. Also it can be tricky implementing the thumbnails into different jQuery plugins.

I think Timthumb also stores multiple versions of images

IMO these-days post thumbnail is a must have option, it’s a trend that’s why WP implemented this feature

also We can re-size it

    set_post_thumbnail_size( 300, 100, true );

    set_post_thumbnail_size( 300, 100, true );
to
    set_post_thumbnail_size( 400, 200, true );

while the theme has posts with the first dimensions used it doesn’t automatically resize them to the new dimensions

Thanks for the response. I’ll try it…

For Additional Custom Sizes

if (function_exists('add_theme_support')) {
    add_theme_support('post-thumbnails');
    set_post_thumbnail_size(120, 90, true);
    add_image_size('my-thumb', 480, 250, true);
}

<?php the_post_thumbnail('my-thumb'); ?>

One thing to note, too, is that there are plugins you can use (or tell your buyers to use) that will go through all already uploaded media attachments and make images for your current thumbnail sizes. This is really helpful when you’re developing a site or theme and you keep changing the thumbnail sizes as you work.

For Additional Custom Sizes We can create any number of custom thumbnail sizes quite easily…

if (function_exists('add_theme_support')) {
    add_theme_support('post-thumbnails');
    set_post_thumbnail_size(120, 90, true);
    add_image_size('my-thumb', 480, 250, true);
}

Retrieving Custom Sizes

<?php the_post_thumbnail('my-thumb'); ?>

yes thats very easy but make it so users can change it through the wp-admin panel it wont resize previous posted images

that needs to remain in tact for older posts that were created before WP 2 .9.
