Set these parameters when showing an image. Image parameters can have different values for the header and the footer of the article.
| Default image | The image to use when no image has been found |
| New Mime type |
The mime type of the generated thumbnail. When no option is available, the thumbnail is of the same type of the original image |
| Background color | The image's background color for images with transparency |
| Border width | The border around the images (in pixels) |
| Border radius [CSS3] | The border radius (a value of half the image width will result in a rounded picture, if the width and height are identical) |
| Border color | The border color |
| Shadow width [CSS3] | A shadow to the image (the bigger the value, the larger the shadow) |
| Filter | A filter to apply to the thumbnail
New Use CSS filters to minimize image processing |
| Quality .jpg | The compression for the .jpg image (0..100). 100 has best picture quality but image file size is the biggest. Usually, a quality of 60 gives good results (enough compression to make the file size small but not too much so that the image still looks good) |
| Quality .png | The compression for the .png image (0..9). 0 has best picture quality (no compression) but image file size is the biggest. Usually, 3 to 5 give satisfying results |
| Quality .webp | The compression for the .webp image (0..100). 100 has best picture quality but image file size is the biggest. Usually, a quality of 60 gives good results (enough compression to make the file size small but not too much so that the image still looks good). Note that when an image of WebP type is encountered, a fallback image is also created. WebP support requires PHP 7.1 minimum when using the GD extension. |
| New Quality .avif |
The compression for the .avif image (0..100). 100 has best picture quality but image file size is the biggest. Note that when an image of Avif type is encountered, a fallback image is also created. Avif support requires PHP 8.1 minimum when using the GD extension. |
| New Allow remote access |
Gives access to remote image files (only valid when allow_url_fopen is enabled) when creating thumbnails. |
| New High resolution |
Create additional thumbnails ready for devices with higher pixel ratios (like Retina screens) |
All images use the loading attribute loading="lazy"
An image PHP extension is required for the creation of image thumbnails. The GD PHP extension is used by default. Make sure this extension is available on your service provider's server. The extension will detect this automatically.
New Joomla 4 The extension supports the Imagick PHP image extension. If Imagick is available on your server, you may use it instead of the GD extension. To do so, go to the SimplifyYourWeb extensions System plugin and select the preferred library.
