Not a full answer, but need formatting:

I have seen it before here: http://shiny.rstudio.com/gallery/selectize-examples.html. Look at the "Select a GitHub repo" input.

Using the I() expression within a render call:

selectizeInput('github', 'Select a Github repo', choices = '', options = list(
        valueField = 'url',
        labelField = 'name',
        searchField = 'name',
        options = list(),
        create = FALSE,
        render = I("{
      option: function(item, escape) {
        return '
' +
               '' + escape(item.name) + ':' +
               ' ' + escape(item.description) + '' +
               ' (by ' + escape(item.username) + ')' +
            '
' +
                (item.language ? '
' + escape(item.language) + '
' : '') +
                '
' + escape(item.watchers) + ' watchers
' +
                '
' + escape(item.forks) + ' forks
' +
            '
' +
        '
';
      }
    }"),

Specifically the ' line.

The issue now is to call a unique image for each option, which should also be possible within I().
