A very common, yet frustrating, issue on the Internet is finding a broken link, taking you to an " Error 404 " page (see "missing xkcd comic" 404: Not Found ). The purpose of the page is to tell the user that the content they were looking for has been either moved or deleted or was never there in the first place.
Randall has suggested replacing the standard "page not found" text, to "This content is not available in your country". This could fool the user into thinking the media they are looking for is actually there, but is region locked , which is another great source of frustration for Internet users. Using a VPN and/or TOR to try and access the content from another country wouldn't work, because it isn't actually region locked; it is just an error 404 page, wasting even more time, most likely frustrating the user a great deal in the process. Error code for "content blocked for legal reasons" is actually 451 , referencing Fahrenheit 451 .
The title text suggests setting the picture as a national flag. This would be very ironic, as it would suggest that the country's flag itself, something that is used to represent the country across the globe, is region locked. The country in the title text likely does not refer to the United States, but rather to the new country featured in 1815: Flag . The first flag of this country included a phone notification bar, so changing it to a "page not found" icon would continue with a trend of technology imagery. Instead he argues for a green puzzle piece, which was Firefox's icon for add-ons (it is now a light blue puzzle piece that changes color or becomes monochrome depending on context). He also argues for an equally frustrating broken image icon (which is used in lieu of a photo that is either missing or incompatible with the browser).
Most modern desktop browsers can extend its capabilities by allowing third-party programs to integrate into its browser. In most browsers, there are two types: extensions, which uses the technologies already available on each respective browsers, and plug-ins which adds new technologies on webpages. Extensions are now more commonly used as they only used browser-approved methods to provide their services while plug-ins are full-fledged computer programs which means that plug-ins are less secure (with the popular plugins like Flash and Java having newly-discovered security problem nearly every day). Fortunately, plug-ins are on the way out, however visitors of older sites that relies on plug-ins will see a "plugin missing" message (which is previously a real message, now a misnomer as plug-ins are being phased-out).
The "broken image icon" is the icon that a browser shows instead of an image when that image can't be found or when the browser doesn't recognize it as a valid image. It is similar to the icon shown when the image has not been loaded yet (such as in the rare case when the browser is set to not load images until requested, in order to save on bandwidth, or if the connection is too slow to load pictures quickly), which is commonly a simplified picture frame containing a simple painting or picture, except on Firefox where it appears to be a blank document. The broken image version usually has a corner cracked off the picture frame. Usually a broken image icon is the result of the source picture being moved or deleted from the location referenced, or if there's an error in the reference (like the filename being misspelled).
