Are these single or possibly multiple attachments?
If the jpgs are not downloading in your browser, then how are you getting them to OneDrive, which should be relying on the same url to upload the image in the flow?
(If you are pulling from the automated JotForm confirmation email, and you do not need the pictures until maybe 20-40 minutes after submission, then I definitely suggest working with the OneDrive url upload instead. JotForm just often has a delay in loading their documents to those urls, so you have to adjust the retry settings on the OneDrive URL action to include more retries & longer intervals.)
Incidentally, if you want a simpler set-up, you should be able to...
-Upload the image by the OneDrive url action,
-Use a OneDrive Get contents action to get the image file,
-Delete the OneDrive file that was uploaded,
-Then use the image file contents from the OneDrive Get contents action in a SharePoint Add attachment action or SharePoint Create file action to add the image to SharePoint (If you Add attachment then it can be immediately associated with your SharePoint item in a gallery, if you Create file in a separate folder, then you'll need to use naming conventions in the flow to create a pattern in the URL that you can recreate using the associated SharePoint record's values)
