Your message doesn't match your Subject question. I'll take it as TWO questions.
1. My personal photos are chronilogical.
2. As to the second item, there are software photo databases that do such. Today, these are quite expensive running in the 10K+ dollar range for the ones that do image processing to add textual items such as "9 people in a park setting" or "14 cars in a parking lot." After the image program runs, then you can search the text database.
Today, most can use a image database and people do the work of filling in descriptions. Such photo software without all the smart image recognition is cheap.
In closing, I will not research this area for you, but will note that such is out there.
I need to put together an image library that will hold tens of thousands of images.
I will need additional properties for each image -- classifications like people, events, buildings, etc.,
I need a good way to search based on those properties. Does anyone have experience/opinion on extending
and scaling photo album for something like this?
