Hi @Jtaylor95 ,
I have made a test for your reference.
1. Here is my SharePoint list.

2. Here is my flow.
_api/web/Lists/getByTitle('listname')/items(@{triggerOutputs()?['body/ID']})?$select=ImageColumnName
json(body('Send_an_HTTP_request_to_SharePoint')?['d']['ImageColumnName'])['fileName']
concat('/SiteAssets/Lists/yourfoldername/',variables('image1filename'))
<img style="display:block;" src="data:image/jpg;base64,@{body('Get_file_content_using_path')['$content']}" alt="ImageColumn1" border="0" width="300" height="300">


Result Screenshot:

Best Regards,
