The platform uses Azure Blob Storage for two distinct purposes:
  1. Media assets — product images and category images served via a public CDN URL.
  2. Quote request attachments — files uploaded by customers when submitting a price request, stored in a SharePoint Document Library Drive.

​
Media assets

Media images are hosted in the webcms Azure Blob container and served from: 
https://webcms.blob.core.windows.net/media
This base URL is set with NUXT_PUBLIC_MEDIA_BASE_URL and exposed to the client. The @nuxt/image module is configured to allow this domain: 
// nuxt.config.ts
image: {
  provider: "ipx",
  domains: ["webcms.blob.core.windows.net"],
},
Reference images in components with the public base URL: 
<NuxtImg
  :src="`${$config.public.mediaBaseUrl}/categories/gran-formato.jpg`"
  alt="Gran formato printing"
  width="800"
  height="600"
/>

​
Quote request attachments

When a customer submits a price request with a file, the Nitro handler uploads it to a SharePoint Document Library that is backed by a OneDrive/SharePoint Drive. The Drive is accessed through the Microsoft Graph API using the configured drive ID.

​
Folder structure

Each attachment is stored under: 
{baseFolder}/{requestKey}/{filename}
For example: 
price-requests/pr-2026-03-abc123/artwork-final.pdf
Defaults:
SettingDefault value
Library nameAssetsProducts
Base folderprice-requests
Max file size25 MB (26,214,400 bytes)

​
Allowed MIME types

The following file types are accepted by default: 
application/pdf
image/jpeg
image/png
image/svg+xml
application/zip
application/postscript
The allowed list is comma-separated in CRM_ATTACHMENTS_ALLOWED_MIME_TYPES and split at runtime.

​
File metadata stored in SharePoint

After a successful upload, the CRM price request list item is updated with:
