Attach image to a chat?

[matt-o-matic]

How can I use this API wrapper to attach an image to chat? I assume I would upload the image then attach a reference to it in the chat instance, but i am not sure. I don't see any examples of any of the client types using an uploaded file.

As it turns out I was wrong in my approach. When using GPT-4o you can simply add images to your user content.

$createParms = [
   'model'=>'gpt-4o',
   'messages'=>[
      ['role'=>'system', 'content'=>'Your system message like you are a helpful AI assistant to do X',
      ['role'=>'user', 'content'=>[
         ['type'=>'text', 'text'=>'Plain text here, if any'],
         ['type'=>'image_url', 'image_url'=>['url'=>'<<<INSERT URL OR BASE64 ENCODED DATA HERE>>>'] ],
         ['type'=>'image_url', 'image_url'=>['url'=>'<<<INSERT URL OR BASE64 ENCODED DATA HERE>>>'] ],
      ],
   ],
];

$result = $client->chat()->create($createParms);

Basically enter whatever would be in the src attribute of an img tag. So not JUST base64, but in the format of DATA:blahblah.

There might be other ways of doing this, but this certainly seems to work for the Omni model.
