When you name images so that they can show up in image search, what's your preference? What do you think is the best naming convention of the three below?
That is the question at Search Engine Watch Forums.
The advice posed asks the particular individual to go to an image search (e.g. Google Image Search) and see the naming convention for particular image search results.
Marcia also says that she's tried both hyphens and underscores and both seem to work well for her.
Underscores or hyphens both work. I use hyphens for filenames and underscores for images just out of habit, I've done it for so long.
The thread also takes a small tangent. Be careful when naming photos. In the particular thread, adding descriptions or adjectives such as "sexypic" might imply that the site is not "kid friendly."
