Email image attachment preview (pre Photoshop) is different than image file

I saved an image from the web to my desktop, which I then tried to attach to an email. I selected the file in the finder, but an earlier pre-Photoshop version of the image came up as the preview. How is this possible?
In this case, the saved image was a picture of 3 clones of the same person. The preview showed only one of that person (no evidence of Photoshop effects)

You have not provided any information that would allow troubleshooting.

it sounds like you attached the wrong image.
