Marlene - I would love to hear what others have to say as I have struggled a lot with this myself. I have boxes and boxes, and I've barely made a dent.
What I have found is that sorting by original photo album is not all that helpful. I didn't put the original albums together, so their organization meant nothing to me and I have many images of the same people from different sources. What was valuable were the images inside the original albums and labeling who they were and approximate dates. You might know these individuals, but your children or grandchildren probably won't. I organize genealogy images by family name, with appropriate folders and subfolders, and then some images that are special, too broad, have too many people to adequately label, or don't have any people, I will plug into folders organized chronologically.
For instance, say you have a group image of the family, taken Christmas 1940. I would label it as such: 1940_12_25 Smith John Jane Dick Sallie. This image I would save within a folder called "Smith John+Doe Jane 1937," which is the couple and the year they were married. So many images are of family groups that I found it easiest to break down by before the marriage and after the marriage. For instance, an image of Jane Doe as a child with her siblings would be in a folder featuring her parents called "Doe Sam+Johnson Mary 1910," and it might be titled: ca 1915 Doe Jane Joe Margaret. If you have a family member with a lot of individual images, you can always create a subfolder just for him or her, either as a child or a married adult.
Sometimes, when something might be more importantly remembered by date, I will copy it into a chronological folder. This is how I have organized my personal family digital images: Year, Month, Occasion. So going back in my chronological folders, I have folders from the year my husband and I graduated (the pre-digital era), my grandparents' wedding, or these amazing old images from my great aunt's honeymoon trip, which show vintage landscape scenes and their jalopy, but don't have that many with people. This system means I might have about three locations to search for a specific image, but I have a fair idea where and when to look.
I have an Epson flatbed scanner, and it has the ability to scan multiple images and separate them. There is also a prefix mode, which can help save time typing with groupings. For instance, you can type in the date or a name as a prefix, set the folder save location, and it will chronologically number them after that. Depending on the level of detail, that prefix tool alone can save a lot of typing and naming.
I know this is far from perfect, but it is what I've managed to work out. Can't wait to hear of some better, more efficient ideas, though!
