Getting full image size from Dataverse table Image Column into an Azure Blob Storage

I have a flow that I am pulling an image column from my dataverse table. I am using a list rows to get my image, then a compose with a base64ToBinary expression (base64ToBinary(outputs('Get_a_row_by_ID')?['body/cr370_pictureoftank'])), then putting the compose output in my blob content for a create blob. This flow works to get my images into the blob storage, but my issue is the images are thumbnails and I can't figure out how to get the full image size from the dataverse. It seems like the only way to pull the image is getting a base64 encoded data, but how can I get the full image? It is stored as a full image in the dataverse

I would like my full image to come into the blob, not a thumbnail.

When you download the image use full in the image size. Otherwise it defaults to thumbnail.

Well that was simple! Thank you, I still can't seem to get that data from the download a file or an image to the blob storage as an image. If I just place the content from download a file or an image it shows all encoded base64 data. But when I try to decode the data it gives me an error because it is an object.

Try this:

base64ToBinary(body('Download_a_file_or_an_image')?['$content'])

Ya I have tried that but I keep getting this error:

I have tried converting the content from the download a file or an image to a string first too and that doesn't work either.

The output from the Download a file or an image looks to be a string and base64:

Just for some reason if I put the content directly in the content for the create blob it shows up in my blob as this:

Please note that I am digging into the object with the ?['$content']. When I ran a test it worked with that schema, but did not without the extension.
