Outputs statistics once all images have been handled. Note: If your source and destination are the same, it's recommended you use this, and options.sigFile, as it prevents you from continually uploading already compressed images each time you run the task options.summarize/summarise If your source is the same as your destination (images are written over themselves), and you want to use the signature checking feature, set this to true

Signatures are based off the unminified source image, so that when the source changes it will be re-minified and re-written to the destination file. Compress JPG and PNG images in your store with TinyPNG, reduce your stores page size, make your store load much faster and save a lot of disk space. When an image is minified, the md5 signature is determined from the unminified source image and written to the file at options.sigFile (a suggested location would be somewhere under your source control). Use the TinyPNG - Compress a PNG image action A tool for building the processes, logic, and direction within workflows. When the signatures match, the file is skipped from being minified again, allowing you to better stay within your API request limits. If set to a filename, it will compare existing source file md5 signatures against those found in the file's json data. Your TinyPNG API key to use for requests options.sigFile If type is not object, string presumed (the API key) options.key Sets options described below from its properties.
