Upload an image to a page using the REST API

[Rob Bell]

I'm trying to use the Confluence REST API to create a page containing an image. I've tried a few different things without success but thought I might be on to something by base64 encoding an image and setting it as the source for an image tag in the page HTML, but although Confluence appears to create the page successfully, it doesn't display the image and appears to strip it out. 

curl -u user:pass \
-X POST \
-H 'Content-Type: application/json' \
-d '{"type":"page","title":"new page 123",
"space":{"key":"DEVELOPMEN"},"body":{"storage":{"value":"<img src=\"data&colon;image/png;base64, iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg==\" />","representation": "storage"}}}' \

Is there a more sensible approach that I'm missing?
