First about the
<p> tags. These are controlled by the ptype setting. If you want your output to start and end with p's, then your ptype setting is correct,
normal. If you don't, then use ptype
block. Your current setting is
normal, and this will give you what you have in your sample html for the screen shot,
p at the start of the output and closing
p at the end.
Secondly, the plugin's resulting html for the image. You don't show what this looks like. Your basic code looks OK but if you are not getting what you want, I would suspect that the problem is here, perhaps something in the format of the response from airtable or your handling of that response.
