Title: Post Thumbnails activation Last modified: August 19, 2016 --- # Post Thumbnails activation * [RankAhead](https://wordpress.org/support/users/rankahead/) * (@rankahead) * [15 years, 5 months ago](https://wordpress.org/support/topic/post-thumbnails-activation/) * Hi, * I am wanting to activate post thumbnails in wordpress 3.01. I have followed the following posts on how to do that: * [http://www.onextrapixel.com/2010/03/19/practical-uses-for-the-post-thumbnail-function-in-wordpress-2-9/](http://www.onextrapixel.com/2010/03/19/practical-uses-for-the-post-thumbnail-function-in-wordpress-2-9/) * [http://justintadlock.com/archives/2009/11/16/everything-you-need-to-know-about-wordpress-2-9s-post-image-feature](http://justintadlock.com/archives/2009/11/16/everything-you-need-to-know-about-wordpress-2-9s-post-image-feature) * I add this add_theme_support( ‘post-thumbnails’ ); * code to my functions.php file in the theme/themename * I then head back to admin area to check and see if I can use thumbnails in posts but it does not show up. * I must be missing something? * Can anyone help? or suggest something… * thanks Viewing 12 replies - 1 through 12 (of 12 total) * Thread Starter [RankAhead](https://wordpress.org/support/users/rankahead/) * (@rankahead) * [15 years, 5 months ago](https://wordpress.org/support/topic/post-thumbnails-activation/#post-1754399) * Any ideas anyone? Not sure why this is not set right out of the box. * Thread Starter [RankAhead](https://wordpress.org/support/users/rankahead/) * (@rankahead) * [15 years, 5 months ago](https://wordpress.org/support/topic/post-thumbnails-activation/#post-1754422) * bump… * Thread Starter [RankAhead](https://wordpress.org/support/users/rankahead/) * (@rankahead) * [15 years, 5 months ago](https://wordpress.org/support/topic/post-thumbnails-activation/#post-1754423) * Here is the 2010 theme Functions.php can someone please copy section where I should add the text and make an example? * _[Code moderated as per the [Forum Rules](http://codex.wordpress.org/Forum_Welcome).

I’ve read [Mark Jaquith’s post on WordPress Thumbnail Images](http://markjaquith.wordpress.com/2009/12/23/new-in-wordpress-2-9-post-thumbnail-images/) and [Matt Brett’s post on WordPress Post Thumbnails](http://mattbrett.com/workshop/2010/wordpress-post-thumbnails-revisited/) and [Matthias Kretschmann’s post on Using The New Post Thumbnail Feature](http://www.kremalicious.com/2009/12/wordpress-post-thumbnails/) and tried to follow the instructions as closely as possible, but the Post Thumbnail box is not showing up in the editor. * I’ve tried it with other themes, too. Not sure what the problem might be or how to track it down. Just getting nothing. * [wagonlips](https://wordpress.org/support/users/wagonlips/) * (@wagonlips) * [15 years, 4 months ago](https://wordpress.org/support/topic/post-thumbnails-activation/#post-1754586) * To experiment, I downloaded and installed WordPress 2.9.2 and, like magic, the thumbnail feature appears just like all those people said it would. * The weird thing is that everything you’re supposed to do to make it work appears to have already been done in the TwentyTen theme. But I’m seeing nothing. * Oy, according to [this thread](http://wordpress.org/support/topic/post-thumbnails-in-twentyten-theme-not-working?replies=3), which points to [this post](http://www.keleko.com/2010/setting-up-post-thumbnails-in-wordpress-3-0-with-twenty-ten/), getting those thumbnails working again is going to require some hacking. * [esmi](https://wordpress.org/support/users/esmi/) * (@esmi) * [15 years, 4 months ago](https://wordpress.org/support/topic/post-thumbnails-activation/#post-1754587) * Have you tried: * – deactivating **all** plugins to see if this resolves the problem? If this works, re-activate the plugins one by one until you find the problematic plugin(s). * – [resetting the plugins folder](http://codex.wordpress.org/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F) by FTP or phpMyAdmin? Sometimes, an apparently inactive plugin can still cause problems. * – re-uploading the wp-admin and wp-includes folders from a **fresh** download of WordPress? * – increasing the memory available to PHP? [http://wordpress.org/support/topic/253495#post-1017842](http://wordpress.org/support/topic/253495#post-1017842) * [wagonlips](https://wordpress.org/support/users/wagonlips/) * (@wagonlips) * [15 years, 4 months ago](https://wordpress.org/support/topic/post-thumbnails-activation/#post-1754588) * Thanks, esmi. I’ve actually installed fresh completely clean installations of WordPress, so as to eliminate any possibility of random plugins (or anything else) from being involved. Although, I did just now increase the memory_limit in the php.ini to 64MB, just to give it a shot. But sadly, no change. * It’s looking, to me, like the functionality changed between 2.9.2 and 3.0.1, with the “Post Thumbnail” feature being renamed “Featured Image” and not really being a thumbnail feature at all anymore. * Unless, do you have Post Thumbnails working in 3.0.1? * [esmi](https://wordpress.org/support/users/esmi/) * (@esmi) * [15 years, 4 months ago](https://wordpress.org/support/topic/post-thumbnails-activation/#post-1754589) * In the Admin pages, the post thumbnail is refereed to as “Featured image”. * [wagonlips](https://wordpress.org/support/users/wagonlips/) * (@wagonlips) * [15 years, 4 months ago](https://wordpress.org/support/topic/post-thumbnails-activation/#post-1754592) * Thanks, esmi. I can see from the number of posts you make that you’re very busy, and I appreciate your taking the time to look at my problem. * So, the thing I want is the Post Thumbnail feature. The way [Mark Jaquith described it here](http://markjaquith.wordpress.com/2009/12/23/new-in-wordpress-2-9-post-thumbnail-images/). It may be that in 3.0.1 it’s being referred to as the “Feature Image” function now, but it’s not working the same way, at all. * Do you think you can help me figure out how to make it show a thumbnail in the loop but the full image on a single page? * [esmi](https://wordpress.org/support/users/esmi/) * (@esmi) * [15 years, 4 months ago](https://wordpress.org/support/topic/post-thumbnails-activation/#post-1754593) * If you follow Mark’s article, you should be able to add post_thumbnail support to your theme. But you still have to insert the image in the page content **and** set it as the featured image. * [wagonlips](https://wordpress.org/support/users/wagonlips/) * (@wagonlips) * [15 years, 4 months ago](https://wordpress.org/support/topic/post-thumbnails-activation/#post-1754594) * Ok, thanks.
