I use a formula in the Key field so as to name the image as I need it to be.
The formula is something like this : [Name]&""&[ID]
But I noticed that the image name is “ID”“Name”.Column name.1234
So, it seems that the order is not respected and also the "" is omitted.
For example, an image with Name = “TEST” and ID = " nkqtbYx0" gets this name : nkqtbYx0TEST.Logo.095418.jpg
Thanks for your help
