Hi, I have a custom article type that has a chatterfeed called by
<knowledge:articleRendererToolBar articleId="{! $CurrentPage.parameters.id}" canVote="true" showChatter="true">.
Im not sure how to have an upload button to select a file, and then when i press upload, it pushes the file as a post to the chatter feed.

In general, I want the exact same feature as the file upload button in the chatter feed, but with custom "choose file" and "upload" buttons in the 
visual force page. Thanks

I have a wrapper class this holds 3 custom article types which are made in the org. Now that I have the wrapper class, I'm not sure how to work the find() function with my wrapper class because my wrapper class is not an object in the org, and I cannot SOQL with it. Heres my code with the VF page and Controller.

Here I have this code:

{!IF(p.Staff_Pick__c = TRUE,$Resource.ThumbsUp,' ')}

If staff pick is checked off, I want it to display a thumbs up image from resource, otherwise its an empty space. But when I have this line of code, it just shows
/resource/1399044523000/ThumbsUp instead
