Generate and Store AI Images with DALL-E and Azure Blob Storage

Description

Beginner’s Tutorial: Manage Azure Storage Account Container & Blob with n8n

> This beginner-friendly n8n workflow shows you how to generate AI images using OpenAI, store them in Azure Blob Storage, and manage blob containers, all with zero code.

👤 Who’s it for

This workflow is perfect for:
Beginners learning Azure + OpenAI integration**
No-code developers** experimenting with image generation
Cloud learners** who want hands-on Blob Storage use cases
Anyone who wants to automate storing AI-generated content in the cloud

⚙️ How it works / What it does

🖱️ Trigger the workflow manually using the Execute Workflow node.
✏️ Use the Edit Fields node to input:
containerName (e.g., demo-images)
imageIdea (e.g., "a robot holding a coffee cup")
📦 Create a new Azure Blob container (Create container).
🤖 Use an OpenAI-powered Prompt Generation Agent to craft the perfect image prompt.
🎨 Generate an image using OpenAI’s DALL·E model.
☁️ Upload the generated image to Azure Blob Storage (Create Blob).
📂 List blobs in the container (Get many blobs).
🧹 Delete any blob as needed (Delete Blob).
(Optional) 🗑️ Remove the entire container (Delete container).

🔧 How to set up

🧠 Set up OpenAI
Create an OpenAI account and get your API key.
In n8n, go to Credentials → OpenAI and paste your key.

🪣 Set up Azure Blob Storage
Log in to your Azure Portal.
Create a Storage Account (e.g., mystorageaccount).
Go to Access Keys tab and copy:
Storage Account Name
Key1
In n8n, create a new Azure Blob Storage Credential using:
Account Name = your storage account name
Access Key = key1 value

> 📝 This demo uses Access Key authentication. You can also configure Shared Access Signatures (SAS) or OAuth in production setups.

Run the Workflow
Enter your image idea and container name.
Click “Execute Workflow” to test it.
