I remember the day when the training wheels came off my bike and it was glorious. The feeling of success you can only feel as a child when you have mastered something you think you should do. They didn't come off because they were no longer cool. They were never cool to begin with. And you didn't have much say in the matter anyway.
I am willing to believe that balance bikes to proper bikes is a better learning experience, according to the boffins. That doesn't mean though that anybody who learned on training wheels is inferior. People who learned to ride a bike like that also won the Tour de France.
Do you mean off Drive or Photos? Images saved from Drive should be ready to go once unzipped. If they came from Photos each image is divorced from its meta data, which comes in a separate file. So you need to check if the new service or software you're using can reunite those two or you need to find a tool online to do that first. They make it deliberately a pain in the posterior to leave Photos.
