Photo gallery in SIv moving to SV.. they disapeared

I have a Samsung Galaxy SIV.. I organised my photos in folders there. I upgrated to S G V, when I go to Gallery or Photos, most photos are not there, only the ones in dropbox or picasa... I assumed they were all saved to Google plus at least, but they are not there or the folders. Any idea?
