From Ner Software:
With Photos Labeler you can add labels to your photos and images. Does your camera add dates to your photos? Are the dates clear? right positioned? at the right size? Would you like to add other labels such as names and places? Photos labeler automatically gets the date when the image was created and labels it on the image. You control the position, size and color of the label. Using Photos Labeler you can add dates or any other labels to tens or hundreds of images at once.
What's new in this version:
