* Plugin Name: ShortPixel Image Optimizer |
| 4 |
* Plugin URI: https://wordpress.org/plugins/shortpixel-image-optimiser/ |
| 5 |
* |
| 6 |
* Compatibility Description: Ensures compatibility with ShortPixel Image Optimizer. |
| 7 |
* |
| 8 |
* We don't need to download image to server from GCS to optimize image. As it can directly use GCS URL. |
| 9 |
* |
| 10 |
* @todo Use backup version of image on Regenerate and Sync with GCS. |
| 11 |
* @todo Restore image now download from backup dir then upload to regular GCS path again. We need to fix that. |
| 12 |
* https://cloud.google.com/storage/docs/renaming-copying-moving-objects#copy |
| 13 |
* @todo implement a customized version of ShortPixelMetaFacade::getURLsAndPATHs() function. |
| 14 |
* @todo convert GCS URL from http://storage.googleapis.com/udx-ci-develop-alim/ to http://udx-ci-develop-alim.storage.googleapis.com |
