Hello JD,
The reason you are probably not getting any images to appear is because the google drive links are not in the correct format that the database reads the URL. The URL has to end in .png or .jpeg
Go to your live database and test this out.
This is my test image:
This is the link to this same image on Google Drive: https://drive.google.com/file/d/1aFjdVVfXyNTTlNNlsCR67sXF4Zj7KNYq/view?usp=sharing
Link to this same image on TinyPic (free image hosting website): http://i64.tinypic.com/16gh6r4.png
When you paste the link that does not end in .png it will give you an error in your database, therefore it will not read it …
So your solution is to find a free image hosting site to upload all your images ---- preferably one with bulk upload but that can still give you the individual URL for each image. (Label them to help you with SEO.). Or you can upload them into your wix media folder (which is what I think you were trying to avoid ---- if not — this is a solution you may want to think about). Either way … they will take a long time to be uploaded … and you will need the individual URL for each and every picture regardless unless you want to upload one by one through and upload button connected to your database.
Then after you have a valid URL for each picture make a spreadsheet, convert to CSV, then upload CSV into your database.
