So I'm trying to find the best solution to display multiple images (currently stored as SharePoint list attachments) in HTML/PDF.
I tried it from PowerApps (more info on this thread), but gave up and am now trying to pull off the images directly from my SharePoint list through my flow.
In the dynamic content of my SharePoint list, there are options 'Thumbnail Small', 'Thumbnail Medium' and 'Thumbnail Large'. There's also 'Thumbnail' which is all 3 sizes. I presume these are the thumbnails for the list attachments. However, even though I have image files in the item attachments that I'm testing out, no images come through in the HTML file.

Is there something else I need to do to get this to work?
I don't receive any errors - it's just that the thumbnail is blank. It seems that thumbnails apply more to document libraries than lists. There is an option called Full Path but I think that's just the server relative url - it's in the format Lists/ListName/ID_.000
I tried to explore using 'Get attachment content' as this would give me 'AbsoluteUri' which works to display a media file in PowerApps. But I'm getting a file not found error with it. If anyone has ideas on getting this to work, that would be great.
Otherwise I think I'd have to look at a flow to move the attachment files to a SP library then do a lookup to those thumbnails. It seems unnecessarily complicated though!
