(DM-8) Working with Images and Attachments

You may have seen some references to the ability to embed images and attachments into your messages. In this lesson we dig into all the details of how to work with these types of files and messages!

The Big Picture - Embedding and Linking Files

You may not be aware, but there are technically two different ways that an image or attachment file can be sent in an email.


Embedding a file involves turning its content into a mass of encoded text, and for that text to be added to the bottom of the more readable text that you wrote in your message. All modern email systems are capable of recognising this encoded text, and decoding it to display the image or file download link when the email is received.
This is the method most commonly used when you send image and attachment files using systems such as gmail. When sending a single email to a few people in such a system, it is the easiest method to use.


Linking involves first uploading the image or attachment file to a web server where you can then obtain a link to the address where it is located. This link can then be included in an email or a text message that you send.
This method involves the extra step of uploading the file, but once this is done, it enables you to reference that file much more easily if you are sending many different messages.

And Workshop Angel Uses...?

So you first upload the file to our file server (at files.workshop-angel.com) where it is given a unique name, and you can then link to the file again and again as you send different messages for your activities.

Important to Know

It is very important for you to know that...
A file uploaded to a file server in this way could have its contents found by a search engine. If you want to send out PDF files with sensitive information in, we suggest you use an alternative method for this which is discussed at the end of this lesson...

How to Upload Files

You can upload a file by going to one of these locations:
  • Messages - Images
  • Messages - Attachments
  • When editing a message, clicking on [Images] or [Attachments] from the local menu.
This opens the File Upload window, either for images, or attachments. The process of uploading either is the same, so we will follow the process for an image.
  • Click on the [Upload New Image] button
  • Click on [Choose File]
  • Choose the image from your hard drive
The image will upload.
The app has the idea of giving the image or attachment a name:
  • Add a name in the Image name field
If you are immediately wanting to add a link to the file into your message, then:
  • Click on the URL/link shown at the bottom of the window. This will copy it to your clipboard.
When you have finished, click on [Close] to close the File Upload window.

Adding An Image To an Email

There are two stages to adding an image to your email. The first is to have the image URL in your paste buffer, and the second is to add the image into your message.

Capturing the Image URL in Your Paste Buffer

There are two ways to do this.
If you have just uploaded an image and clicked on the link at the bottom of the File Upload window then you will have the URL in your paste buffer.
If you wish to use an image that you have previously uploaded:
  • Click on [Images] on the local menu.
This will bring up the Manage Images window.
  • If necessary, use the search to find your selected image
  • Click on the link/URL of the image shown in its entry
This will copy the link/URL to your clipboard.

To add an image to your message:

  • Start editing the message
  • Store the image link/URL in your paste buffer as described above.
  • Navigate to where you want the image to appear in your message
  • Click on the
    [Picture] icon in the text editor
This brings up the Insert Image window:
  • Paste the file link from your paste buffer with keys [ctrl]-v (PC) or [Apple]-v (Mac)
  • Click on [Insert Image]
The image should now appear in your message!

Recommendations About Image Sizes

When you embed images in your emails to create a more graphic design style, you need to pay attention to the size of the image that you use. This is because when the email is read on a mobile phone, if you use an image that is too wide, it often causes the text of the email to appear very small.
We recommend that any image you embed is no more than 500 pixels wide for this reason. You may need to experiment with the image width a little to get the look that you want for your message both on mobile phones and laptops.

Adding an Attachment to an Email

You will be adding your file to the email as a link in the email text your write, rather than as an actual attachment.
Follow these steps:
  • Start editing the message
  • Store the file link in your paste buffer as described above.
  • Create some text in the email to reference your file, for example "Click here to download our reading material for the workshop."
  • Select the text you wish to be the link, e.g. "Click here".
  • Click on the
    [Link] icon in the text editor menu
  • Paste the file link from your paste buffer with keys [ctrl]-v (PC) or [Apple]-v (Mac)
  • Click on [INSERT LINK]
The words "Click here" will now be a link to your file.

Attachment Method for Sensitive Information

As we discussed earlier, if you have some sensitive information in a PDF or Word file, this could potentially be found by the search engines and read by others. If this is the case, we recommend that you actually send the file from your conventional email system where it will be embedded into the message you send.
To do this:
  • Go to contacts, and search for the group of people you wish to send the message to (e.g. all attendees of a specific activity).
  • Click on [Add all to list]
  • On the right hand list side, click on [Email List]
The Copy Contact List window pops up:
  • Set list type to "Email bcc list"
  • Click anywhere inside the list to copy it to the clipboard
  • Click on [Close Window]
  • Now create the email in your own email system, pasting in the email list you just copied to the To: or Bcc: fields.
  • Create and send the email.


We have discussed the two ways that image and attachment files can be included in an email - by embedding, or by linking. We have looked at how Workshop Angel uses the linking method, and how to use the user interface to upload your file and obtain a link to where it is stored. We've then looked at how to include that link in your email, both for images and for attachments.
Finally, we have discussed how attachments that use the linking method could be found by a search engine, and looked at an alternative way to send attachments which are embedded in an email sent from your own email system.
Finally in this chapter about defining messages, we are going to talk about working with Text/SMS messages.
