Before: [![Screenshot 2021-08-06 at 09 24 31@2x](https://user-images.githubusercontent.com/329880/128480831-0e9bcbf2-e2f1-4b4d-a7ac-1ea93fdcee2b.png)](https://user-images.githubusercontent.com/329880/128480831-0e9bcbf2-e2f1-4b4d-a7ac-1ea93fdcee2b.png) After: [![Screenshot 2021-08-06 at 09 29 37@2x](https://user-images.githubusercontent.com/329880/128481538-4e60c3b8-8a26-4042-979d-f4a0ad97a506.png)](https://user-images.githubusercontent.com/329880/128481538-4e60c3b8-8a26-4042-979d-f4a0ad97a506.png) It also increases the size of thumbnail images to ensure they remain crips on HiDPI/Retina displays. Installation ------------ [](#installation) 1. Install module via composer: ``` composer require purplespider/silverstripe-clearer-thumbnails "1.*" ``` 2. Perform a flush: ``` https://www.example.com?flush=1 ``` 3. For Silverstripe 4: For sites with existing assets, run the generate-cms-thumbnails task to re-generate the thumbnails for the Files tab (otherwise no thumbnails will appear). ``` php vendor/silverstripe/framework/cli-script.php dev/tasks/MigrateFileTask only=generate-cms-thumbnails ``` Silverstripe 5 doesn't provide the MigrateFileTask anymore. What exactly does this do? -------------------------- [](#what-exactly-does-this-do) It simply overrides some settings via a [config file](https://github.com/purplespider/silverstripe-clearer-thumbnails/blob/master/_config/clear-thumbs.yml) to: 1. Change `ThumbnailGenerator` `$method` from `FitMax` to `Fill` which avoids thumbnails being generated too small and then stretched. 2. Doubles the `UploadField` `$thumbnail_width` and `$thumbnail_height` from `60` to `120` to ensure thumbnails are crisp on HiDPI/Retina displays. 3. Increases the `Image` `$asset_preview_width` and `$asset_preview_height` to ensure image previews in the Files area are crisp on HiDPI/Retina displays. Notes/Tips ---------- [](#notestips) - On sites with lots of images, the migration task is a resource intensive process which can take a while. Use `cpulimit` to limit the effect it has on the site, e.g. `cpulimit -p 1234 -l 50` - Possible issue with assets in a symlinked location not getting updated via the migration task, suggest temporarily replacing the symlink with the assets dir before running the task if you experience this. ### Health Score 40 — FairBetter than 88% of packages Maintenance63 Regular maintenance activity Popularity20 Limited adoption so far Community14 Small or concentrated contributor base Maturity54 Maturing project, gaining track record Bus Factor1 Top contributor holds 81.3% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
