-The enclosed images folder holds the image files used as the title screen for the game. All common formats such as PNG, JPG, and GIF are supported.
-Byond's DMI format is also supported, but if you use a DMI only include one image per file and do not give it an icon_state (the text label below the image).
-
-Keep in mind that the area a title screen fills is a 480px square so you should scale/crop source images to these dimensions first.
-The game won't scale these images for you, so smaller images will not fill the screen and larger ones will be cut off.
-
-Using unnecessarily huge images can cause client side lag and should be avoided. Extremely large GIFs should preferentially be converted to DMIs.
-Placing non-image files in the images folder can cause errors.

-You may add as many title screens as you like, if there is more than one a random screen is chosen (see name conventions for specifics).

-
-Naming Conventions:
-
-Every title screen you add must have a unique name. It is allowed to name two things the same if they have different file types, but this should be discouraged.
-Avoid using the plus sign "+" and the period "." in names, as these are used internally to classify images.
-
-
-Common Titles:
-
-Common titles are in the rotation to be displayed all the time. Any name that does not include the character "+" is considered a common title.
-
-An example of a common title name is "clown".
-
-The common title screen named "default" is special. It is only used if no other titles are available. You can overwrite "default" safely, but you 
-should have a title named "default" somewhere in your DMI file if you don't have any other common titles. Because default only runs in the 
-absence of other titles, if you want it to also appear in the general rotation you must rename it.
-
-The common title screen named "blank.png" is also special. It is only used to fill space while the real title screen loads. You should leave this file alone.
-
-
-Map Titles:
-
-Map titles are tied to a specific in game map. To make a map title you format the name like this "(name of a map)+(name of your title)"
-
-The spelling of the map name is important. It must match exactly the define MAP_NAME found in the relevant .DM file in the /_maps folder in 
-the root directory. It can also be seen in game in the status menu. Note that there are no spaces between the two names.
-
-It is absolutely fine to have more than one title tied to the same map.
-
-An example of a map title name is "Omegastation+splash".
-
-
-Rare Titles:
-
-Rare titles are a just for fun feature where they will only have a 1% chance of appear in in the title screen pool of a given round.
-Add the phrase "rare+" to the beginning of the name. Again note there are no spaces. A title cannot be rare title and a map title at the same time.
