I am sorry to go off track here, but this is relative to this topic. As my grandmother would have said, "Don't put all of your eggs in one basket."
Consider several options and other alternatives for saving images. I am no expert for sure, but there is a mantra: backup, backup, backup. I do like to have images available on my computer to be able to add to documents, genealogy programs, and more, but I save them several places.
I have many images that are old family photos, documents and historical information that I have collected over several decades in my pursuit of family history, which was basically found one piece at a time, driving 1000's of miles, and 1000's of hours searching and researching. No one had done it before me, but there are many who have copied it since.
Some of what I have is virtually irreplaceable if it were to go missing. There were family photos that are missing, probably destroyed by second wives, also known as wicked step-mothers. (One of my g grandfathers was a millionaire 100 years ago, in a small town, but lost his first wife at age 36, leaving 4 young children behind. The second wife, 4 years later, had all of the children by the first wife fleeing the household, due to her antics. There are a few wonderful photos from that family, but many were probably destroyed by her wicked self) Knowing how much work I have into gathering all of this, I have also done a few things to put it in various places so that I can have it, if one source fails.
I believe that anything that is saved anywhere--internet, computer, storage devices, etc.--can disappear. None of this is infallible. I suggest that if you value it, have multiple sources for saving it. Backp, backup, backup.
Some alternative places to store, and I know there are others that I have not mentioned. Photos take up lots of space, so save selectively.
1. Dropbox--an online storage. You get x amount free when you sign up, but it won't store 1000's of photos. You can pay for more storage, maybe $79.99 a year. I haven't and won't do that, but others have. You can earn more storage by inviting others to join. I have acquired lots more storage by inviting many other people. I have many of my family history documents and information here as one source of storage.
2. External hard drive--There are a few varieties available with a variety of sizes available, all for a fee.
3. Flash drives--I have had one fail, and was grateful that I had backups in other places, but they do work for storing much information in a small place. If you are in the right place at the right time, you can get them for free at trade shows, etc. They are small and lightweight, so are an easy way to keep photos and documents when moving from one computer or location to another.
4. Hard copies--I try to keep hard copies of photos especially, but when I find historical documents, such as my grandfather's military records, I print them out and keep them in plastic pages in notebooks by family groups. When I travel, I take my notebooks and interested family members can page through and see all of what I have collected. The danger of notebooks is that people may "want" this photo or that photo. (See 5 below) I have had photos lifted out of my notebooks, but have tried to be able to make photos replaceable if this happens.
5. I have uploaded photo images to a few places where photos can be purchased. The closest place for me to have photos processed is a Walgreens pharmacy. You need an account, and like photobucket, could go away any day, but has worked for me for now. (I know there are several places online where photos can be uploaded and saved) You can invite others to access different albums for their own use. When my grandmother died, I got a box of negatives of my mother's childhood and other family, while my cousin got the photos that I worked on labeling and organizing with my grandmother. I scanned all of those negatives and let people know they could access them if they wanted to.
I know a large extended family that has an account and everyone belongs. Photos from events, such as weddings, baptisms, family reunions, are all saved there, and anyone who wants to order select photos is able to do so.
6. Blogs--there are a few blogs that are free. You can make them public or private and can save photos there. I have a few private blogs with family information that family can be added to. I have much information there.
7. Closed facebook groups--I have started a few family groups, have invited family members that belong to the group, and have shared many photos and information there. Photos from events and happenings can be saved together in albums, people tagged, and anyone can access them.
One more thing about saving photos:
Label and date your photos. "Mom and Dad" is not enough. "John and Mary Smith, marriage photo, April 1852, Furth im Wald, Bavaria, Germany" is a much better label. Many photos are destroyed or disposed of because once a certain person dies, no one knows who the people in the photos are. I saw a photo album in Nebraska of family members that no one knows who they are, just descendants of my gg uncle Joe. There are two paintings of family members, from the 1800s, painted in Europe, but unlabeled. We know who one person is, but the other person? No one knows, but they are beautiful and well done.
