How can I store images in a knowledge base (vector store), and what is the process for retrieving them later?

[Yonatan_Tesfaye]

I’m working on building a knowledge base using a vector store and would like to store images alongside text data. My main questions are:

1. How can I add images to the vector store?

• Should I convert images into embeddings first, or is there a way to store them directly?

• What tools or integrations (e.g., OpenAI, Pinecone, Weaviate) work best for handling images?

2. How can I retrieve the stored images later?

• If images are embedded as vectors, how can I ensure accurate retrieval?

• Are there specific workflows or nodes in n8n that can help with this process?

Any guidance, best practices, or examples would be greatly appreciated! Thanks in advance!

It looks like your topic is missing some important information. Could you provide the following if applicable.

• n8n version:
• Database (default: SQLite):
• n8n EXECUTIONS_PROCESS setting (default: own, main):
• Running n8n via (Docker, npm, n8n cloud, desktop app):
• Operating system:

Pasting your n8n workflow

---

Ensure to copy your n8n workflow and paste it in the code block, that is in between the pairs of triple backticks, which also could be achieved by clicking </> (preformatted text) in the editor and pasting in your workflow.

```
<your workflow>
```

Make sure that you’ve removed any sensitive information from your workflow and include dummy data or pinned data as much as you can!
