Recently a resident came to me panicked. Her iPhone was running out of memory space.
It soon became apparent that her phone was loaded up with photographs.
What to do?
Obviously, get the photos off the iPhone.
There are a lot of options.
One is to transfer them to a PC or Mac either wirelessly or with a cable.
There are better and easier options, the best of which is to have every photo stored on the cloud the moment it is taken.
The app Picasa was probably the first way to do this though now there are more. A search of how to do it on YouTube will point the way to instructive videos.
Next best is to store them on other media.
Most phones do not have enough storage space for a larger photo library but a few do. The Windows BLU JR phone accommodates Micro SD cards of large sizes. The Moto E phone allows for a micro SD card. Many phones have limits as true size but Microsoft claims that Windows Phones handle any size SD card. The larger ones do get expensive.
I have a 64 G Drive which handles all my music and photos and books on a Windows Phone.
Some tablets allow for memory expansion.
An expandable and inexpensive tablet is the Dell Venue, as is the new Kindle Fire 7. A cheap way to store photos is through such an inexpensive tablet.
If your phone does not provide for memory expansion, and most do not, it is still possible to use a memory device accessible via WiFi, such as WiDrive and others.
PCs and Macs also have lots of space to store photos. If not backed up elsewhere, your photos will be lost when your PC quits.
There are external drives which also exposed to the risk of loss when they fail.
I do not trust PCs or external drives for reliable storage, however.
Photos should also be backed up on a high capacity USB flash or SD drive. One backup is never enough no matter what type of backup you are using.
