WatermarQue

WatermarQue is a simple application that allows users to lay a watermark on multiple graphic files quick and easy.

Simply, drag and drop a group of up to 10 files to the listbox of the application window. If you like, also, drop a sample graphic file onto the drop box to design a watermark. And then give a go. It's just that simple.
WatermarQue accepts various graphic formats for inputs such as BMP, GIF, JPEG, PDF, PNG, PSD (Photoshop) and TIFF. For both Mac and Windows versions, WatermarQue is capable of exporting watermarked images in BMP, JPEG, PICT and PNG.
