th23 Upload – Intro video

This plugin 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 on your webserver, while serving the pages faster to your visitors due to the reduced image size.

Watermark your precious images with the Professional extension, 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.


More details about the plugin capabilities:

  • Original aspect ration of uploaded images will be kept, preventing automatic cropping.
  • Optionally specify a suffix to be added to names of resized images, 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.

More details about the Professional extension:

  • Select image sizes to watermark, eg to exclude thumbnails.
  • Mass-add/-remove watermarks for already uploaded image attachments.
  • Chose location of the watermark on the image and maximum width/height to cover.

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