Picturesque lets you apply the same effects to a collection of images and save them all at once. This is much less tedious than doing each image at a time.
You can repeat this step as many times as you like to add more images. If you are uncomfortable with drag and drop, you can repeatedly choose the Add Image command from the File menu.
You can use the arrow buttons at the bottom right to see how the effects look on different images in the collection.
To remove an image from the collection, use the arrow buttons to display the image and choose Edit > Remove Image. You can also remove all images by clicking the Cancel button.
