2. Connect your account

Questions about n8n

Here are the details most teams check before getting started.

Is WriteAlt available on n8n Cloud?

Yes. WriteAlt is now a verified community node on n8n Cloud. Search for WriteAlt from the canvas and install it. Self-hosted instances can use the verified node or install n8n-nodes-writealt.

Why can I not find or install the node?

Ask your instance owner or admin to check that verified community nodes are enabled. Only owners and admins can install nodes; once installed, other members can use them.

Can I process more than 10 images?

Yes. Ten is the maximum number of requested languages per image, not the number of incoming items. Map one accessible image URL per item. Credits, service limits, and n8n execution limits still apply.

Can I upload a local image or paste a spreadsheet URL?

The node needs an accessible image URL, not binary uploads or spreadsheet links. Read the spreadsheet or parse a CSV first, then map each image URL.

Does the node save results, and how are credits charged?

The node returns alt_text and language versions in alt_texts. Add a destination node to save them. Each image-language combination uses one WriteAlt credit; n8n costs are separate. Review descriptions in their page context before publishing.

Add WriteAlt to your next n8n workflow.

Find the verified node, connect your API key, and test your first image.
