From the options provided, which method is most efficient in loading a page quickly?
When determining how to handle file locations, the best approach depends on various factors. If all files are stored locally on a server, using the File.Exists() method would be efficient for quickly checking their existence and replacing them if necessary.
However, if the images are located on a remote server or website, implementing a JavaScript solution may be more appropriate. While this approach could be slightly slower for users due to loading times and additional checks, it allows for seamless swapping of images when needed.
If you simply want to display a "image not available" image in a clean way, the most efficient option is to utilize Javascript. Making the server access the filesystem for this purpose is unnecessary extra effort for a small presentation detail.
