Re: Embed sharepoint list attachment as html in email

Hi @ccqn ,

You don't need the get file content control, please delete it.
Replace the dataUri formula with the formula I provided you.

I did a test for your reference.

In my scenario:

The Result:

My Flow:

<img src="data&colon;image/@{body('Get_attachment_content')['$content-type']};base64,@{body('Get_attachment_content')['$content']}" alt="GG">

Best Regards,

Sunshine Gu

Hi @ccqn

Alternatively, use the below expression with dataUri function:

<img src='@{dataUri(outputs('Get_attachment_content')?['body'])}'>

Pls just copy & paste the above expression in the flow.

If this helps & solves your problem, please remember to give a 👍 and accept my solution as it will help others in the future.

Hi @ccqn ,

I'm surprised why your pictures can't be displayed because I used the same method as you.

Could you please create a simple flow like mine, without other controls and html formats, just to check whether attachments in SharePoint can be embedded in the email body?

<img src="data:@{body('Get_attachment_content')['$content-type']};base64,@{body('Get_attachment_content')['$content']}" alt="GG">

I know this is a silly question, just to make sure your attachment can be opened in the SharePoint list, right?

Best Regards,

Sunshine Gu

Hi @v-yetonggu-msft
Just tried without any other controls and html format and I still can't embed any image. I can open the image from Sharepoint. Not sure if this will help but this is how I attached the image from Microsoft Forms to Sharepoint.

Hi @ccqn

Its look like attachment file size issue.

I faced the same issue on embedding gif image with around 1 MB in size, but the same flow worked for smaller gifs:

Solved: Re: Add GIF image into the email body - Power Platform Community (microsoft.com)
