FAQ
- What does “Custom upload structure” mean?
-
The custom upload structure can be easily set in the media settings of the Pro version. Here is a little example how the WP standard upload looks like:
wp-content/uploads/2016/11/myimage-150×150.jpg
… and after you set a custom upload structure it can look like:
wp-content/uploads/2016/11/thumbnails/medium/myimage.jpg
Reviews
September 9, 2019
This review is for the Premium version! The task was to migrate a Joomla! page to WordPress and the customers were not happy with WordPress´ media file management. They used to create a physical folder per blog post, add the images for this post and create a slider out of all images in this folder. WordPress had to be tricked into that sort of media management with the help of @mguenter´s plugins "Real Media Library" (free) "Physical Custom Upload Folder" (premium) and Real Thumbnail Generator" (premium). What is special about this plugin? There are a few plugins out there that allow generation of a physical upload folder within /wp-content/uploads. The thing is: WordPress automatically generates thumbnails for every image within the folders and adds them to the folder. So, the sliders contain not only the images themselves, but the thumbnails as a "bonus". This plugin allowed me to generate the thumbnails in a sub-folder, so they are not added to the sliders. Yay! Works perfectly well, saved me some coding time and is, as far as I found, the only plugin to do so.
