For several front side images, it is the only one technical possible solution to add them together right now
Also: Which photo should be used for product photo when some product have more than 1 front sides?
For recycling instructions, it can be used in case when different elements of packaging have separate instructions that are credited in different parts of packaging instead of whole picture with many irrelevant information between them.
But Iām not for this practice. I prefer separate pictures for every side and it is not really comfortable to so in the app. I just recognized suddenly it is possible and someone can do that in future. So I decided it is better to ask about it and define project policy about collages
