can I upload multiple photos at once? batch upload?

Do you mean to ask to allow the user to upload multiple files? If so, yes. It is possible to upload multiple files to the form by enabling Allow Multiple option from the properties of upload button.

By enabling this option, you can upload multiple files using one upload button and you can also drag and drop files to the upload button. Please be noted that there is a limit of 25 files to upload into a Upload field.

Hope this information helps. Please get back to us if you need any further assistance. We will be happy to help.

Thank you!
