Every image in Denada comes with a set of tools for managing, replacing, and enhancing your visuals. Click directly on an image in the editor preview to access these options. The ⓘ button next to the image label in the Edit tab takes you to the image in your image collections, where you can view its full metadata and use it across other projects.

​
Crop image

Choose Crop image to crop directly within Denada. You can freely adjust the crop area or lock to a specific aspect ratio and drag to reposition. Useful for tightening the composition or removing unwanted edges. The crop is specific to this block in this project — it does not change the original image in your collections.
If your image appears too tightly cropped in the block, try uploading a higher resolution version with more negative space to give yourself more room to work with.

​
Inset image

Choose Inset image to add padding around your image inside its slot — handy for logos or product shots that need breathing room instead of filling the whole area.

​
Image format

Choose Image format to control the format the image is served in: Auto (default, based on the uploaded file), JPEG, GIF, or PNG. The image server optimizes all images for email rendering — so you don’t need to worry about compression or file size when you export.
  • JPEG — best for photos and lifestyle images.
  • PNG — best for graphics, logos, or images that need transparency.
  • GIF — animated images (use sparingly — large GIFs can slow email load times).

​
Flexible height

When enabled, the image display area adapts to the natural height of your image instead of locking to a fixed aspect ratio. This is typically turned on for hero images and full-width lifestyle shots where you want the full image to show. When turned off, the image is cropped to fit the block’s predefined dimensions — useful for keeping a consistent grid layout. You can also leave it on the library’s default. Toggle it on and off in the editor to see the difference.

​
Alt text

Denada automatically generates descriptive alt text for every image. Alt text is displayed when images don’t load (common in Outlook) and is read by screen readers for accessibility. Choose Alt text in the image menu to edit it to be more specific or brand-aligned.
Good alt text describes what’s in the image, not what the email is about. “Person wearing wireless headphones on a couch” is better than “Shop our new product.”

​
Replacing images

There are several ways to swap an image, listed under the Replace section of the image menu.

​
Upload image

Drag and drop directly onto the image in the editor, or choose Upload image to browse your computer for a file.

​
Add image from URL

Choose Add image from URL and paste a direct image URL. Useful when pulling product shots from your website or CDN.
You need to provide the full hosted image URL (e.g., https://website.com/images/image.jpg). Denada cannot extract an image from a regular webpage URL through this option. To do that, use the Chat tab — click on the block, then ask Denada to use an image from a URL.

​
Paste from clipboard

Choose Paste from clipboard to paste an image directly from your clipboard (screenshot, copied image, etc.).

​
Auto-generate image

Choose Auto-generate image for AI-powered image generation from a text prompt. Type a description of the image you want and Denada will generate it. You can select from multiple AI models. Learn more about AI image generation →

​
Remix image

Choose Remix image to edit your existing image with AI. This lets you modify what’s already there — add elements, change backgrounds, adjust styling, or completely transform the look while keeping the subject. Remix aspect ratio options:
  • Match aspect — keeps the current image proportions (default).
  • Square — 1:1 ratio.
  • Landscape — wider than tall.
  • Portrait — taller than wide.
Example remix prompts:
  • “Remove the background and place on solid black”
  • “Add a gym environment in the background”
  • “Change the lighting to dramatic side-lit”
  • “Extract just the product on a clean white background”
You can attach reference images in the remix prompt for style transfer — upload a mood board image and ask “match this lighting and color grade.”

​
Pick from images

Choose Pick from images to browse your team’s image collections. Use the collection dropdown to filter by category. Two search modes are available:
  • Similarity — searches AI-generated descriptions of each image. Great for finding images by what’s in them (e.g., “headphones on dark background”).
  • Keywords — searches exact terms and metadata. Best when you know the file name or tag.

​
Use dynamic source

If your library has a scripting language configured, Use dynamic source replaces the uploaded image with an ESP expression (like {{ event.ImageURL }}) that becomes the image source at send time. Learn more about dynamic content →

​
Delete image

Choose Delete image to remove the image from the block. The image is not deleted from your collections.

​
Additional image actions

The image menu also includes:
  • View fullscreen — opens the image at full size.
  • Open in new tab — opens the image in a new browser tab.
  • Copy image URL — copies the hosted image URL to your clipboard.
