This is a sub-page of Roblox (Windows, Mac OS X).
Although a lot of Roblox's image files are exposed in the content folder, there are a lot of files directly baked inside of the RobloxStudioBeta.exe file. There are plenty of unused images to be seen in there.
Unused Graphics#
Unused Explorer Icons#
Inside of Roblox Studio's exe is a sprite sheet for the Explorer class icons.
Each icon is a 16x16 image spread out across a single row of roughly 96 icons. 
Although most of the icons in here are used, there are a couple of icons in this sprite sheet that remain unused.
Unused Explorer Icon #1#
The first unused icon is the 27th icon in the sprite sheet.
This icon was previously used for the DHTML feature, which was disabled in early 2008 due to security issues, and later removed entirely.
Unused Material Sprite Sheet#
There exists an unused sprite sheet image for Roblox's material palette.
Roblox Studio currently just uses individual images for the materials instead of a sprite sheet.
This image is notably out of date, as new materials have since been added. It also uses the old 'R' stud texture for some reason.
Unused Alternatives For Used Images#
There are some images in Roblox Studio that share the same purpose, but only one of them ends up being used.
Unused DPI Measurement Image#
To provide an accurate physical scale for device emulation, Roblox provides a method of measuring your screen's DPI by having you place a card up against your screen that can be scaled to match the proper DPI.
Currently this screen uses a fictional 'Roblox University' card, but previously it used a fake credit card for its image instead. This was probably changed so that it looked less fishy.
