Multiple Attachments

the best practice here is to have a child Table for your attachments. That way you can take advantage of the built-in feature that Quickbase has for multi file attachments. Juiced Technologies also has an add-on with a few more features that does the same thing. The advantage of this, especially if you were uploading pictures from a computer or a phone is that you just select multiple pictures(or on a computer drag and drop),  push the button and create multiple children with very few clicks.
