Define parameters for the JPEG files exported by the gallery.
Most CE4 plugins export two images renditions, Large and Thumbnail.
Set the width and height threshold for large image renditions. Images are resized to fit Width & Height. Large image renditions are exported into the /photos/ folder within your saved gallery folder.
Set the width and height threshold for thumbnail image renditions. Images are resized to fit Width & Height. Thumbnail image renditions are exported into the /thumbnails/ folder within your saved gallery folder.
Defines the renditions' relationship between image quality and file compression. Smaller numbers offer less visual fidelity and smaller files; larger values offer greater visual fidelity and larger files.
For Web images, we recommend a quality setting not higher than 76. Beyond that threshold, image file sizes increase dramatically with negligible improvement to visual fidelity.
