Can you still add photos in that section? On the info. it says attachments enabled, but I can't find an attachment thing when I go to add a photo to a post..?

To add a picture.

Add the post as normal.
Then view the post and click the "attach" link to upload your picture. Make sure you check the box marked "Embed".

If you have added a post in the past, you can go back and upload a picture now if you wish
