Power Pages allows users to upload and display images using forms, file fields, or through custom components. This feature is especially useful for user profiles, product catalogs, event posters, and document portals.
Common Use Cases
- Uploading profile pictures or ID proof
- Displaying product or event images
- Letting users attach images to feedback or forms
How to Upload and Display Images in Power Pages
1. Set Up a File Column in Dataverse
To store images:
- Go to Dataverse > Tables
- Choose or create a table (e.g.,
Customer,Product, etc.) - Add a column of type File (not Image), or use the Image column for auto-display in some views
2. Create Entity Form or Basic Form
- Add an Entity Form or Basic Form component to your webpage.
- Include the Image or File field in the form configuration.
3. Enable File Upload Control
When configuring the form:
- Under the file/image field, enable the file control so that users can browse and upload.
- You can also limit file types and size.
4. Displaying the Uploaded Image
Method 1: Auto Display (Image Column)
If using an Image column type in Dataverse:
- The uploaded image automatically shows in form views and lists.
Method 2: Custom Display Using Liquid
To display an uploaded image stored in a File column:
{% assign file = entities.files[0] %}
<img src="{{ file.url }}" alt="Uploaded Image" width="300px" />
Or for an image field:
<img src="{{ entity.image_url }}" alt="Image" style="width:300px;" />
Ensure the image is published and accessible via proper web roles.
5. Custom HTML Upload (Advanced)
If you want to build a custom uploader using JavaScript:
<form method="post" enctype="multipart/form-data" action="/_services/upload">
<input type="file" name="uploadedfile" />
<button type="submit">Upload</button>
</form>
Requires authenticated context and customization to handle the POST and link file to record.
Security Tips
- Ensure only authenticated users can upload files.
- Use Web Roles and Table Permissions to control access to file/image fields.
- Limit allowed file types to images only (
.jpg,.png, etc.).
Best Practices
- Optimize image size before upload for performance.
- Use thumbnails in listings; link to full-size images when needed.
- Consider storing metadata (uploaded by, uploaded on) alongside images.
