Frequently Asked Questions
Common questions about Auto Smart Thumbnails
No. AST works silently in the background. If your site has many existing thumbnails, you can remove them manually by 'Tools -> Auto Smart Thumbnails' or 'Installed Plugins -> Auto Smart Thumbnails -> Remove Unused Thumbnails'.
AST doesn't remove the default thumbanil which is defined by WP and WP uses it frequently.
A list of removed files is available after a cleanup, When a cleanup is done, a message will show how many images is removed. Click on the number to show the list.
Not as I know. Your WP website will continue working as is. But your uploads folder will be lighter. It helps save your server storage and makes backup easier and faster.
Turn on debug and you can check what's going on. Check 'Log debug info for troubleshooting' in 'Settings -> Auto Smart Thumbnails'. After that, you will see a button 'Get Debug Log' in 'Tools -> Auto Smart Thumbnails'. It shows up when there is info logged after a cleanup is done. Leave a note with your url and the logged info in the support forum and I will try my best to help. Or you can join Discord forum to see if I or anyone there can help.
This is because your server doesn't respond. AST needs to know how many images need to be processed. When it happens, as explained above, turn on debug, leave a note with the url in the support forum.
To downsize or re-compress image png files to jpg needs to change database. To keep the data and files in sync needs a lot messy code. So I decided not to do it. My suggestion is to use XnViewMP to convert the png to jpg before uploading it to your media library. XnViewMP can do batch coversion and amazing color correction. It got only one drawback that it can't decide the target size intellgiently as AST does. You need to manually calculate the size to downsize to and different images may need seperate calculations.
At the moment, there are two plugins: 'SmartCrop' by late Alex Mills (Viper007Bond) and 'WP SmartCrop' by 'Burlington Bytes'. The later provices a tool for users to set a focal point manually. Alex's SmartCrop plugin uses Smart Cropping Class/algorithm developed by Greg Schoppe, which is based on color difference and image entropy and puts the focus of the image at or close to the photograph rule of thirds line. It doesn't do face detection. AST is the first and only WordPress plugin that does smart crop with face detection. I do hope it inspires people and more people join to explore the latest technologies and make it helpful, and more fun.
WordPress 5.3 introduces a new way to manage a big image by checking if its height or its width is above a big_image threshold (the default value is 2560px), and scaling down it to big_image. This is a nice feature that WordPress has big images in check. AST does it in a different and better way. It scales down images by a factor of an integer which means no fraction of pixcels and no bluring. And WordPress checks only new uploads. AST will check all the images, existing or new. Note the new feature in WordPress 5.3+ will automatically scale down large pictures. So the downsize function in AST won't be triggered.
