The site I’m trying to create is a virtual art gallery for individual members and I would like each individual member to be able to upload their own photos to their gallery with ease for other people to see.
hey!
You can set up an upload button and then onChange trigger the upload and update (insert) your database:
https://www.wix.com/corvid/reference/$w.UploadButton.html#startUpload
https://www.wix.com/corvid/reference/wix-data.html#insert
Your gallery can be connected to the database and so you will get pictures coming to the gallery from that database that will be updates with the pictures that your users upload.
