Opis

Regenerate Thumbnails allows you to regenerate the thumbnails for your image attachments. This is very handy if you’ve changed any of your thumbnail dimensions (via Settings -> Media) after previously uploading images or have changed to a theme with different featured post image dimensions.

You can either regenerate the thumbnails for all image uploads, individual image uploads, or specific multiple image uploads.

Ottimo plugin, molto utile per riaggiornare le immagine nel Template dopo modifiche. +++

Wow

It’s amazing how obviously ancient this plugin is if you look at the screenshots, yet it still keeps being updated and it still works great. Nice dedication, thanks for the great plugin.

Always in my design toolkit

When I design custom themes for clients, this plugin is a necessity. Its part of my default ‚install plugins’ pack when I start with a new project. A lot of the times it is necessary to tweak the size of Featured Images, especially testing the responsive side of things.

A huge time saver in some instances

I find this plugin most useful when working on e-commerce sites, but when it’s required, it’s a huge time saver.

Useful plugin

After 5 month of usage i can say that it is one of the useful plugin and also i can give my rating as 5 stars.
useful to re generate thumbnails.

Does a decent job of doing what I don’t want to do

I needed a plug-in to regenerate image thumbnails for a client. They have roughly 1,300 images stored and served through AWS/CloudFront. We only needed thumbnails regenerated, but this plug-in is regenerating ALL image sizes, not just thumbnails. As a result, it’s doing 5-10x more work than it should, and it’s timing out without any error messages after the first few hundred. It also failed to generate thumbnails for one of our images and gave reasons as „unknown” – not very helpful. I think it’s because the image is a tif, but that would be pretty easy to return as useful error message, so I’m not sure that’s it.

WordPress refers to its images as „Image Sizes” and specifically the smallest of those is „Thumbnail.” The plug-in should be called „Regenerate Image Sizes” so its name matches what it actually does. Or at least make it clear on the plug-in page that your plug-in is using terminology differently from WordPress to avoid confusion.

I gave this two stars because at least it did perform image resizing, even if it was for a bunch of image sizes it wasn’t meant to resize.

Log zmian

Version 2.3.1

Fix PHP notice. (#20)

Version 2.3.0

Maintenance release. A major rewrite is in the works on GitHub.

Add „Regenerate Thumbnails” button to the Edit Media submit metabox. Props Brian Alexander for inspiration.
Bump required WordPress version to v3.2 so that we don’t need to bundle jQuery’s progress bar plugin anymore.
Context for translators.

Version 2.2.6

PHP 7 compatibility.

Version 2.2.5

Updates relating to plugin language pack support.

Version 2.2.4

Better AJAX response error handling in the JavaScript. This should fix a long-standing bug in this plugin. Props Hew Sutton.

Version 2.2.3

Make the capability required to use this plugin filterable so themes and other plugins can change it. Props Jackson Whelan.

Version 2.2.2

Don’t check the nonce until we’re sure that the action called was for this plugin. Fixes lots of „Are you sure you want to do this?” error messages.

Version 2.2.1

Fix the bottom bulk action dropdown. Thanks Stefan for pointing out the issue!

Version 2.2.0

Changes to the Bulk Action functionality were made shortly before the release of WordPress 3.1 which broke the way I implemented the specific multiple image regeneration feature. This version adds to the Bulk Action menu using Javascript as that’s the only way to do it currently.

Version 2.1.3

Move the error_reporting() call in the AJAX handler to the beginning so that we’re more sure that no PHP errors are outputted. Some hosts disable usage of set_time_limit() and calling it was causing a PHP warning to be outputted.

Version 2.1.2

When regenerating all images, newest images are done first rather than the oldest.
Fixed a bug with regeneration error reporting in some browsers. Thanks to pete-sch for reporting the error.
Supress PHP errors in the AJAX handler to avoid sending an invalid JSON response. Thanks to pete-sch for reporting the error.
Better and more detailed error reporting for when wp_generate_attachment_metadata() fails.

Version 2.1.1

Clean up the wording a bit to better match the new features and just be easier to understand.
Updated screenshots.

Version 2.1.0

Lots of new features!

Thanks to a lot of jQuery help from Boris Schapira, a failed image regeneration will no longer stop the whole process.
The results of each image regeneration is now outputted. You can easily see which images were successfully regenerated and which failed. Was inspired by a concept by Boris.
There is now a button on the regeneration page that will allow you to abort resizing images for any reason. Based on code by Boris.
You can now regenerate single images from the Media page. The link to do so will show up in the actions list when you hover over the row.
You can now bulk regenerate multiple from the Media page. Check the boxes and then select „Regenerate Thumbnails” form the „Bulk Actions” dropdown. WordPress 3.1+ only.
The total time that the regeneration process took is now displayed in the final status message.
jQuery UI Progressbar version upgraded.

Version 2.0.3

Switch out deprecated function call.

Version 2.0.2

Directly query the database to only fetch what the plugin needs (the attachment ID). This will reduce the memory required as it’s not storing the whole row for each attachment.

Version 2.0.1

I accidentally left a check_admin_referer() (nonce check) commented out.

Version 2.0.0

Recoded from scratch. Now uses an AJAX request per attachment to do the resizing. No more PHP maximum execution time errors or anything like that. Also features a pretty progress bar to let the user know how it’s going.

Version 1.1.0

WordPress 2.7 updates — code + UI. Thanks to jdub and Patrick F.

Version 1.0.0

Initial release.
