Won’t Playback photos taken

[photoeyebymzj]

After I took the photos at my event I went home to upload them and all was there and didn’t load. But I shot them all for the event. Changed my sd card once both were ready for use with no photos on them. How can I get those photos to playback

can you view them on the camera?

what is the model of the camera? and what did you upload them to?
