Support » Fixing WordPress » How to create thumbnails manually

  • I’ve been uploading images via ftp to my server, because the image uploader in WP didn’t work for a month. Now this issue is solved, I have tens of images that don’t have a thumbnail. I would nevertheless get thumbnails for these, because it makes searching for them on a later moment easier. Is there anyway to force WordPress to check all uploaded images, and create a thumbnail if none is found (so similar to the process that was performed after upgrading from 2.3 to 2.5)?

  • I have a similar issue. I tried the the Add From Server plugin, but this failed to generate thumbnails for me. Is there a way of tapping into WP’s thumbnail generating fuction (I can’t find it anywhere) to do this? Specifically, I would like to write a little script that queries the posts table for images and then inserts these as ‘attachments’, calling the thumbnail generator for each? Is this possible…does anyone know how? Thanks for reading 🙂

    Try the regenerate-thumbnails from viper. I haven’t fully tested it, but it appears to work.

    <b>Wow</b>. This plugin did exactly what I needed. Thanks to the google gods for pointing me to this post on my first search, and to Viper for satisfying a very specific need.
