Requested images
The following images are requested by BGA:
- game_box.png
- It is displayed on the main site on the game description page and when creating a table (280x280 px).
- It should be an image of a physical copy of the game box as it appears in an online shop.
- It is better to take the version of the game that is coherent with the game art used in the adaptation, and from the original publisher of the game.
- The background of the image must be transparent.
- game_icon.png
- It is the icon displayed in the lists of games and tables (50x50 px).
- This one should not be transparent, and shouldn't have a border (a black border will be add by BGA).
- The objective of this icon is to make the game recognizable among the other games. A good idea is to take a part of the game cover that is distinctive (ex: the game title).
- publisher.png
- It is the logo of the publisher of the game, displayed on the game description page.
- The width must be 150 px. The height can be anything. The image could be transparent.
- publisher2.png (optional)
- If the game has been co-published by 2 publishers, you should upload a second image named "publisher2.png" (same characteristic than the first one).
Game art
You must upload in img directory all images of your game interface.
Images loading
Be careful: by default, ALL images of your img directory are loaded on a player's browser when he loads the game. For this reason, don't let in your img directory images that are not useful, otherwise it's going to slowdown the game load.
Note that you can tune the way images are loaded with Javascript method "dontPreloadImage" (see Game Interface Logic).
Images format
You can use 3 image format while building your game interface:
- jpg images
should be used for non-transparent images. Jpg are usually lighter than Pngs, so please choose Jpg for big pictures (ex: game board, cards) when you don't need transparency to accelerate game load.
- png images
should be used for transparent images.
- gif images
can be used for animated images. This is not recommended to use gif animated images as they can upset players, but for some specific interface element this could be useful.
Use CSS Sprites
To limit the number of images load and make the game load faster, you must use CSS sprites, ie you must gather several images in a single one.
