Uploading additional images removes previous uploaded images from track

[garbast]

I've a track, where I uploaded two images both size 8 MB and 7 MB, saved the track and close the edit form.

I then edited the same track again and uploaded additional two images with 6,2MB and 9,3MB. Saving and closing the form I came back to the track view, in which the first two images are missing.

I don't think that this is what should happen. I'd expect to see all four images.
