Provides the URL of an image file that is used as an icon.

Add-in type: Task pane, Mail

Valid only in these VersionOverrides schemas:

• Task pane 1.0
• Mail 1.0
• Mail 1.1

For more information, see Version overrides in the add-in only manifest.

Note

You must use Secure Sockets Layer (SSL) for all URLs in the <Image> element and any child <Override> elements.

Each icon must have three <Image> elements, one for each of the three mandatory sizes:

• 16x16
• 32x32
• 80x80

The following additional sizes are also supported, but not required.

• 20x20
• 24x24
• 40x40
• 48x48
• 64x64

The following image file formats are supported.

• BMP
• EXIF
• GIF
• JPG
• PNG
• TIFF

Important

• If the image is your add-in's representative icon, see Create effective listings in AppSource and within Office for size and other requirements.
• Office Add-ins require the ability to cache image resources for performance purposes. For this reason, the server hosting an image resource must not add any CACHE-CONTROL directives to the response header. These directives result in Office automatically substituting a generic or default image. To force the use of new icons on your development computer, Clear the Office cache. To force the use of new icons on your end-user's computers, you must give the new icons different URLs from the old ones.
