Edit rich text attachment permissions for model-driven app

Hello,

I have a model-driven app that (among other things) can create email templates that can be sent out in bulk. I have added a rich text editor component to the table column that saves the Body of the email, so that users can format text and insert links and images.

When they insert an image, there are two options - one is to use a Web Resource, and the other is to upload a file.

When users select to upload a file, it doesn't show up in the resulting emails that are sent out. It looks like the problem is that there is security on the location where those image uploads are saved, so anonymous access is blocked.

Is it possible to change the permissions for those images so that they will show up properly in emails? I have found instructions on how to accomplish this in a portal, but my solution is not in a portal, and I can't find equivalent settings.

Thanks.

Let me make sure I understand you correctly, do you store the image that you want to display on your email in a dataverse File column?

Actually, part of the problem is that I don't know where they are being saved.

All I did was add a rich text component to one of my text fields. That allows users to upload images from their computers and embed them in the text field. But I don't know where the uploaded pictures are saved or how to make them public.

If you are using the control in this page https://docs.microsoft.com/en-us/power-apps/maker/model-driven-apps/rich-text-editor-control then the images are stored in Azure Blob Storage https://docs.microsoft.com/en-us/power-apps/maker/model-driven-apps/rich-text-editor-control#best-practices-for-using-the-rich-text-editor

Thanks @Fubar, those links were very helpful in understanding how this works.

After reading through them, my current understanding is that there is no way to make the rich text images available to anonymous users. And therefore, we can't use them in email templates.

I could go in and change which table the the rich text images are stored in, but as long as it is in a Dataverse table (which seems to be my only option), there's no way to make it available to the general public.

The exception to this is that it appears to be possible if you are using a portal. But since I'm not, I think this is the end of the road for this idea.

If someone knows of a way to do this that I haven't thought of, I'd be interested to hear it!

Thanks for your help.
