Primg is a tiny portable tool which allows you to print an entire folder of images in various ways.
Navigate to the folder in an Explorer-type pane and any images it contains are displayed in thumbnails. You can change the number of columns/ size of the thumbnails, set an optional caption for each one to its file name or date/ time taken (according to Exif tags), and choose to display the folder name and page number as a header. A Preview pane updates in each case to display the results.
If you only want to print a single image, click that particular thumbnail and it appears in the "Single" view. Here you're able to resize the image, and/ or drag and drop it into your preferred position on the page. (A "Page Setup" dialog switches you from Portrait to Landscape, if necessary.)
Alternatively, the "Multiple Fixed Form" tab displays multiple thumbnails of your selected image. You're able to choose their width, height, the spacing on the page and the number of images to print in total.
Whatever you're doing, the Print button sends your work to the printer in a couple of clicks.
Primg has a few useful settings available, too, including an Auto Rotation option for JPEGs.
Having to print every image in a folder is a little restricting (we'd prefer to use a drag-and-dropped selection), but Primg delivers much more than we'd expect for a portable 471KB freebie, and if you need more image printing flexibility then we'd give it a look.
