This filter automatically resizes images to their width and height dimensions.
Users never have to worry about uploading pre-sized images again; they can just
insert an image, set its width and height properties, and the image is
automatically resized on output.

Installation and Usage

  • Install this module using the official Backdrop CMS instructions

  • Visit the configuration page under Administration > Configuration > Content
    authoring > Text editors and formats
    (admin/config/content/formats) and click
    'Configure' next to the text editor you want the image resize filter enabled

  • Check the box for 'Image resize filter' under the list of filters.

  • IMPORTANT: Re-order your enabled filters under 'Filter processing order'.

    If using the Image Resize Filter on the 'Filtered HTML' text editor, you MUST

    1. That the <img> tag is in the list of allowed tags, and
    2. That the 'Image resize filter' is run BEFORE the 'HTML filter'.

    If using the Image Resize Filter with BBCode or some other non-HTML filter,
    the 'Image resize filter' must be run AFTER the BBCode filter. If using
    Pathologic, Image Resize Filter
    must be run AFTER the Pathologic filter too, since Pathologic must correct
    image path locations for Image Resize Filter to find the images.

  • Optional: Click the Image resize filter tab underneath 'Filter settings' to
    set additional configuration for the the image resize filter.

  • Further usage instructions can be viewed and edited in the Wiki.
