Is there hidden watermark can be applied in image like companies logo?

Just put your logo on a separate layer and experiment with opacity and blending modes.

Thank you for reply.

I have some images and I want to know if they have hidden watermark or not, please can you help me about this.

Ohhh I gotcha. No sorry I don't know how to do that.

are you trying to circumvent a copyright?

No, I just asking as I found some images related to my company in other company website
so I want to know that, if they applied watermark or not.
Can you help me how I can check this?

ah, gotcha. It would be nice if we could embed invisible watermarks, but that technology doesn't yet exist... that i know of. The one thing which can be done is in the metadata. It's easy enough to change the copyright info. If you download an image and then view using Bridge, you can see what's in the metadata. Or you can open in Ps and go File>File Info.
