Image File Name
In one sentence
The name given to an image file before upload, which the engine reads as a signal about the picture.
Analogy Mental model
Labelling a box before it goes on the shelf, rather than dropping it in a drawer and hoping.
In practice What you actually do
Use a descriptive name with hyphens between the words. A file called pour-over-coffee-guide-step-3 beats DSC-0042 every time, because the filename is one more place a search engine learns what the picture actually shows.
Where people get burned Pitfalls
Spaces break URLs, non-ASCII characters create encoding problems, and camera defaults carry no information at all. Renaming after publication means either broken references or a redirect for an image.
