There is a Demo site built with Rikka, password is rikka, just try it. Because the free docker service provider I used stop it's free plan, the demo is on my personal VPS now. So the password is not given anymore, but you can also visit it and have a look :)



Click Choose button to choose an image.

Input passwordrikka.

Click Upload button.

If no error happened, you will be redirect to preview page:


You will see a "Please wait" message If you uploaded a large file and save process is not finished, just wait a second.

When you see image url, you can click Src, Markdown, HTML, RST, BBCode button to copy image url in that format.

But: Once you close this page, you can't get it back except from browser history(Or you save the url).

This is intentional. The main design concept is simple, just Upload-Copy-Close-Paste, then you can forget Rikka.

BTW: The preview image of Demo site is saved in Rikka too. (But Github will put images which in Markdown files into its own CDN to accelerate access)


Truly image save back-end of Rikka is written as plugins, can be specified by -plugin option.

Please see Rikka Plugins Doc for available plugins.


See Rikka API Doc.
