Overview

The Basic Image module adds the ability to create Basic Image collections, which are capable of displaying GIF, PNG and JPG/JPEG files. Users can view a medium-sized preview of the image on the object's View tab, or click the image to view it full size in their browser. The module creates preview and thumbnail images in the same format as the original image during the ingest process. This module does not use a separate image viewer.

Dependencies

Configuration

Creating image derivatives

To create image derivatives, configure the image processing toolkit to use ImageMagick rather than the GD2 image manipulation toolkit in Administration > Configuration > Media > Image Toolkit (admin/config/media/image-toolkit). If GD2 is selected, TN and MEDIUM_SIZE datastreams will not be generated.

Image derivative quality and scaling

When images are uploaded, ImageMagick creates a MEDIUM_SIZE preview that is 500 x 700 pixels, or as close as possible with the aspect ratio preserved. If the original image is smaller, this can result in low quality preview images. To prevent image upscaling for images under 500 x 700 pixels, go to Administration > Islandora > Solution pack configuration > Basic Image Solution Pack (admin/islandora/solution_pack_config/basic_image) and uncheck the box labeled "Upscale images for MEDIUM_SIZE derivatives?"
