Have you also installed the ejabberd extension? You should refer to this question no how to setup the extension: HTTP File Upload (XEP-0363). You check that the module is enabled from the admin panel.

However, personally I wouldn't use ejabberd to host the files. In the past I've uploaded the files to a standard Apache server and then just sent the image URL via XMPP. This has benefits because it gives you much more control over the files. For example, you could use AWS to host the files and then distribute them over a CDN.
