How can you add your company logo on more than 300 pictures as a watermark from Photoshop, without lose time ?

Open a picture > create a new action named "watermark lorem ipsum" > File > Place > Choose the logo you want to put on your picture > Resize it and put it where you want to place the watermark > Press stop playing in the action window > File > Subscripts > Image Processor > Select the folder you want to watermark > Select the folder you want to place the watermark pictures > Select the type of file you want to create ( e.g jpg. png), select the quality you want for your photos > Select in preferances " run action" and then the action you want to run as you name it e.g "watermark lorem ipsum"  > Press run and wait all the pictures to be watermarked 

My answer is same as ms.  Diana Pirga answer the question :-)
