I don’t get any images in my PDF attachment, just the file name. How do I get the images? Thanks.
AFAIK, it’s expected for form submissions to include the file name rather than the upload itself. I imagine this is due to the fact that in the form, it’s an “Upload button” and supports various media types - e.g. video, audio, archive etc, not strictly images alone. While images may be widely supported in PDFs, some of the other file formats aren’t supported.
When downloading a PDF where a form has an upload field, it makes sense to use the most common piece of information across the uploads that the PDF can support - hence the file name.
If you want to view and access the images attached to the submissions, you’ll want to use the submission table - Wix Forms: Viewing and Managing a Submissions Table | Help Center | Wix.com
Yes, it’s an upload button for an enquiry form for a dentist surgery. With the old forms, the PDF included the images which the client was very happy with.
The upload button is set to images only and is limited to 1 image upload so why not show the image? With the new version of forms the client has to download 8 images per enquiry and put them in a folder. Needless to say they are not happy! Is there another solution?
Noted - there’s no setting to change this at the moment, but will take the feedback with the team 
As Noah mentioned, there is no out-of-the-box solution available as of now, but that being said, if this is an absolute necessity for your client, this functionality can be developed using custom code.
