How to remove fine black outline from image

[GLGracey]

Here’s the issue:  I had a series of images printed and printer's final jpegs to me have a black outline that shows up when I post the images to my web site. I have searched and searched for instructions in how to remove it. I've searched under "frame," "border," "outline," etc. but nothing I've found seems to addres what looks like a fine black border around the image. Can you please show me the way? Many thanks. glgracey
