Hi, I am trying to delete all pdf thumbnails, while regenerating thumbnails for images. I have about 40,000 files in my media library which are mostly pdfs, and none of them need image previews.
I have code in my function.php to disable pdf generation when they are uploaded:
/*=== Disable Thumbnail Generation for PDFs */
function wpb_disable_pdf_previews()
{
$fallbacksizes = array(); return $fallbacksizes;
}
add_filter('fallback_intermediate_image_sizes', 'wpb_disable_pdf_previews');
Is it possible to do something similar with this plugin so that existing thumbnails for pdfs are removed, and none are regenerated when running Force Regenerate?
Thanks!
Hello, thank you for providing such good plugin development.
i’m having a task of setting uploads to CDN, upon done the file transfer(without thumbnails), i would have to regenerate thumbnail from the original images, that are actually stored within the external server directory, at CDN service.
Currently, the setup of CDN is fully supporting uploading with also thumbnails on upload generating, via several WP builtin media filters. Now to use your plugin within this specific setup, i’ve read through the advanced filters scripts you’ve posted at GitHub , so my question is, considering the provided snippet :
// add_filter( ‘regenerate_thumbs_original_image’, ‘my_frt_original_image’ );
function my_frt_original_image( $original_path ) {
if ( false !== strpos( $original_path, ‘bad_original’ ) ) {
return false;
}
return $original_path;
}
-can i set effectively the remote server location as the $original_path //=’cdn.example.com/’ , considering the already explained fully functioning remote upload transferring ? The $original_path set value would only serve as the source locations of the original unscaled images, while the upload part would be handled by the functions of other, the CDN plugin, do you have any suggestion on attaching event/hook with that other function?
Thank you for any further information

]]>does Force Regenerate Thumbnails work with .webp images
]]>Hi, thank you for a great plugin!
The theme uses images, which are stored in its assets folder.
I’m stuck with the one size that they have made.
Same issue with any plugin.
Would be super useful if images that are not in the WP Media Uploads folder would also get thumbnails
Please, consider adding this feature
Thank you!
]]>Hi,
Thank you for the great plugin!
I removed a few thumbnail sizes from my website and used your plugin to remove all the no longer used thumbnails.
That worked on my local machine but not on the live website. After a closer inspection of its code, I noticed that the $file_info used on line 546 of class-forceregeneratethumbnails.php is not previously set. That made the code not delete any images by skipping the unlink action.
The problem was sorted after I added
$file_info = pathinfo( $image_fullpath );before the
$thumb_fullpath = trailingslashit( $file_info['dirname'] ) . wp_basename( $size_data['file'] );
Please have a look.
Best regards,
Giannis
Hi, testing out your plugin ??
so it regenerates all the sizes my theme is using but also regenerate some other sizes also, these ones: : 100×100, 1536×864, 300×300, 600×338, 768×432
any ideas why and how can i stop it?
Hello!
I’ve got a setup that uses Custom Image Sizes by 99 Robots to create sizes, Crop-Thumbnails so that we can modify them, and EWWW Image Optimizer to optimize the files. However, there are a few discrepancies where some older articles don’t have a certain file size created and while I could use the Crop-Thumbnails plugin to generate them individually, I was looking for a solution that could automatically loop through the images in the library and generate just the missing sizes without affecting the existing ones (and hopefully EWWW Image Optimizer would pick up on the size being newly created and optimize it automatically too).
There’s over 8k items in the media library and 20 registered sizes, so I imagine it might need to be done in batches since one long script might time out.
I know it’s not a feature available in your plugin now, but do you think it might be added? If not, I’ll figure something else out. Thanks!
]]>I have my media settings at 150×150 for thumbnails. However after running it nicely delete various other unwanted sizes but it regenerates 100×100 (in addition to the expected 150×150)
Is there any way to make it also delete the 100×100 (no pages are using images of this size)
Thanks
]]>I ran this plugin for the first time. I have a lot of images and it took a few hours. The first 3000ish images worked fine. Then it skipped about 1000 images saying just error 0, then it finished the final 2000 images with no issues.
When the error 0 happened, it provided no image ID like it does when there are some other errors.
Any ideas?
]]>hi great plugin btw, Buti see during the run its deleting certain thumbnails but still keeping five of the default thumbnails. Anyway to delete those as well? Or am I gonna get empty images on posts?
thx
]]>This doesn’t appear to work for PDFs. I’ve had this issue with previous plugins too, only found one that could actually do it but it was a larger plugin for image/thumbnail refinement. Was looking for something quick & simple. Not sure if you’ve tested with PDF thumbnail regeneration or not but figured I’d ask before going back to the other plugin.
]]>Hi!
I have a site that is selling digital files, like PDF and DOCX…
All the files are uploades to woocommerce_uploads folder containing tear and month folders (woocommerce_uploads\year\month)
Is it possible to remove all existing image sizes generated in those folders?
Or
Regenerte only two image sizes and remove all others previously generated sizes?
As for now i tested your plugin and it only regenerates the thumbnails and is not deleting old ones.
]]>Looks like there (still) is a bug for images that are edited in the WP backend and then regenerated with this plugin. For example, if you rotate an image and then regenerate the thumbnails, then the source image is resetted back to the original image instead of the rotated image.
There are the steps to reproduce the problem:
We’ve tried that on different installations, even installations without any other plugins, and its still the same behaviour.
I hope you can reproduce the problem and provide a fix soon
]]>I’m doing some troubleshooting where images I’m bringing in from Flickr via another plugin (Justified Image Grid) are loading slowly. So, I’d like to know why I might use this plugin on my WP site. Might it affect images I am dynamically bringing in to my site (as per above) or is this just for images that have been uploaded directly into my media library?
What effect does this plugin have on thumbnails? Why would I use it?
Thanks.
]]>I would like to have this plugin rebuild thumbnails from a custom plugin where I have the details about a particular image. Is there any way to do this please. Essentially I would like the programmatically click the “Force Regenerate Thumbnails”?link that I see on the media library admin screen.

Hello.
Is there any kind of documentation available? Thanks a lot.
]]>Hi,
is there a possibility to add filter/settings for skip image when it have all sizes right – so if image have all sizes ok, then will be image skipped and not regenerated in Tools -> Regenerate All Thumbnails ?
Secondly if there is a way how add to url same GET param which indicate where in process we are – I have large website with many thousand of images and there will be probably some downtime in process and in this case I must run regeneration from start – I think that here is enough add some param like offset
Thanks a lot
