What should I do if the travel frog photo album is full?

The photo of the traveling frog won't fit. Detailed explanation of the problem:

1. At present, there is no way to expand the photo album in the traveling frog. Players can only choose and keep a reasonable number of photo albums.

2. You can only delete postcards when they are full. This is necessary.

3. In fact, friends don't need to save every postcard, because postcards will inevitably repeat. If it is a duplicate postcard, just ignore it.

Then, if all the repeated postcards have been deleted, it is still not enough, then you can choose those postcards with less rich colors to delete.
