Assistance with image formatting, please?

Hey all,
I'm using Pushover.net for push notifications and it's working very well (reliable, fast and very inexpensive).
The only thing I haven't figured out yet is how to include an image in the notification. I spoke to the developer and he sent me this below, but I have no idea how to convert an image (the output from FFMPEG IP camera RTSP frame grab (or that same image as base64)) into "multipart/form-data".

When sending an image, the HTTP payload has to be sent with a Content-Type of multipart/form-data. Some HTTP libraries don't support this but the popular ones like curl do:

Pushover: API

Would someone be able to let me know what I might need to do to 'translate' this, please?

All the best,
Dax.

Are you using the node-red-node-pushover node ? You should be able to attach the image as a buffer as msg.attachment - use a base64 node to convert the base64 to a buffer and then a change node to move that buffer to msg.attachment.

I'm grabbing the picture from the RSTP stream and save it to disk.
After that it's attached to Pushover with msg.image with the help of a change node

Hey @dceejay, I am indeed, good sir. Thank you, I'll give that a try right now.

Hey @edje11, thanks again for your reply. I finally managed to get everything working, but that revealed a little mistake in the solution you proposed.
msg.image should actually be msg.attachment and once I realised that, I had everything working. (yay!)
