adding jpegs without the photos

The easiest way to add photos to an email and have them not on view at the receiving end is to: 1 - put them in a folder and add the folder to the email; 2 - Control (right) - click on them, select Compress from the contextual menu and add the compressed file to the email.

In apple mail - if you add an image, right click it, and select view as icon - it will show as just the icon.

However the problem with email is you are in the hands of the recipients email app. Even if you choose to send it showing as an icon - it may be that the recipients app will expand that to show the full image. In this case, yes they just have to live with it.

Just by way of example, I sent to emails to my Gmail address. One with the jpg showing as an icon and the other with it showing as in image. In both cases it showed in the browser gmail client as a thumbnail as shown in the screenshot.

One option is to compress the image (or images) into a zip file, and then send that - in that case it won't show as an image, but the recipient will have to unzip it.

Another possibility is to use the web site "we transfer". You can upload your images there, and then get a link to send in the email. When the recipient clicks the link, they are able to download the image files.

A jpeg file is a photo file. Please read the following user tip and restate your question/problem in detail:

Put your image in a zip file and attach that to the email:

Say what now?

A Jpeg without a photo is an empty file.

Can you clarify what you're trying to do? Also, attach to what?
