There are three different ways to get an image, a company logo, a social media icon, a partner badge, whatever, into a signature. Which one you use depends on where the image is coming from and how important it is that recipients actually see it.

Which Method Should I Use?

Insert/Edit Image 

Use this to add a new image directly, whether it's already hosted somewhere or you're uploading it on the spot. 

1. Place your cursor where the image should go, and click the Insert/Edit Image button in the editor. 
2. In the Source field, either paste the path/URL to an already-hosted image, or use the upload icon next to the field to upload a new file, ExSign will fill in the Source field automatically once it's uploaded. 
3. Add an Alternative description, this is the text shown if the image can't load, and it also matters for accessibility (screen readers use it). Worth filling in for logos and icons rather than leaving blank. 
4. Set Width and Height in pixels. The lock icon next to these fields keeps them proportional; leave it on if you resize one dimension and want the image to scale correctly rather than stretch. 
5. Click Save. 

Image Gallery 

Instead of uploading the same logo or icon every time you need it, use the Image Gallery to pick from images already uploaded to ExSign. This is the better option whenever you're reusing an existing brand asset rather than adding something new. 

Where these images actually come from depends on your Image Upload Settings: local storage pulls from the Portal server's assets/images directory, while cloud storage pulls from Amazon S3. Either way, the Image Gallery shows you what's available without needing to know or care where it's physically stored. 

Convert to Embedded Image 

By default, an inserted image is linked - the email references an external URL rather than carrying the image itself. That means recipients have to download it to see it, and if their email client blocks that (a common default in many corporate environments), the image just won't appear. 

For a logo or icon that needs to reliably show up every time, embed it instead: 

1. Select the image in the editor (it can already be there via either method above). 
2. Click Convert to Embedded Image.

The image becomes part of the email itself, so it displays immediately, no download, and no internet connection needed to load it. This matters more for something like a logo that should always be visible than for, say, a time-limited banner where an occasional missed load is less costly.
