DateStamp Batch Stamper for Mac is an easy-to-use application that does exactly what its name implies and allows you to insert date stamps on multiple image files at one time. I'm looking for an app that will read the EXIF from a photo and print the original date/time it was clicked on it I could use IrfanView but it does not support for multiple images, must be done one at a time. Put a date stamp on your photos with uMark's EXIF watermarks. Add watermarks to multiple photos in minutes with the click of a button. Prevent people from stealing your photos with watermark. UMark is a photo watermark software for Windows and Mac. XnConvert is a free program that makes it easy to batch convert and resize images, as well as perform many other actions on images, like rotate and crop, adjust brightness, contrast, and saturation, apply blur, emboss, and sharpen filters, and add masking and watermarking effects.
