Plugin settings (maximum image upload size)

Provides easy admin access to define maximum width and height of uploaded images. Uploads exceeding these dimensions will be resized accordingly. Only the defined maximum size will be stored on the server. This way you will be able to save space and bandwidth and serve pages faster to your visitors due to the reduced image size.

Watermark your precious images, keeping track of them in the internet. New uploads can automatically be marked or you can add/remove watermarks via the Media Library. Unmarked copies of images are kept inaccessible to the public in case you want to restore it.

Additionally th23 Upload offers some further options:

  • Keep original aspect ration of uploaded images, preventing automatic cropping
  • Specify a suffix for resized images to be added to names, eg upload of too large image test.jpg will be stored as test_resized.jpg
  • Set quality for resized images, allowing to save further space and bandwidth
  • Select image sizes to watermark, eg to excluding thumbnails
  • Mass-add/-remove watermarks for already uploaded image attachments
  • Select location of watermark on the image and maximum width/height to cover
  • Supports GD Library and ImageMagick (Imagick)

Usage

This plugin works in the background, even for Admins and Editors of your website.

Once configured all work upon upload of new images happens during the normal process – images are resized and watermarked as per your configuration before they are added in the post / page editor.

See intro videos about functionality and configuration for an overview: Visit the th23 Upload video series on Youtube.

NOTE

Only handles JPG / JPEG images, as PNG (transparency) and GIF (animation) could loose their features upon resizing.!

For manually adding / removing of watermarks visit the Media Library, where you find this function as part of an images row actions, when hovering.
