> Pictures are one way, there are other ways too like writing a journal.
Finding a shoebox full of photos is a lot easier to go through and reading through a journal / diary. One can quickly reminisce with the photos, but it would take a while to read through various written entries.
Photos can also capture spontaneous instants of time, whereas recollecting and writing down something involved taking up the entire context of an event and then 'interpreting' it so you can write it down.
Further, not all of one's internal state can even perhaps be put into words to be written down. A photo may help you recall feelings that you find difficult to put into words.
