Is there a way to switch a default picture that you actually wanted in once of your ace albums but by mistake forgot to hange the app. from default to other album without losing the default date???
you should be able to just go back into the edit and switch the album in your drop down box. It should work as long as you haven't already used that date in the album you want to move it to. Worth a try anyway!
If you need to move a picture you will need to open the picture/edit and then change the album selection, like Jenny mentioned.
