This extension is a further development of canonknipser ImageMagick Thumbnailer. The extension uses the PHP imagick class to modify uploaded images, thumbnails and avatars. It shows a preview image in attachments upload. If the values set in the ACP are exceeded by the image file, the image is being resized by the extension. The extension supports JPEG, WEBP, GIF and PNG images. Other image formats, for example BMP, are converted to JPEG when resized. This extension can change the image size and/or the image file size. It rotate images, thumbnails and avatars according to their EXIF information and it can remove the EXIF data from JPEG and WEBP files. Images and thumbnails can also be rotated manually.
