Cropping & resizing pictures in order to add new items in online games

We run a few free online animals games (see [login to view URL]), with everyday thousands of people from all around the world playing them :) On each of these games, players can use their ingame money to purchase items for their animals in the Shop section: see for instance [login to view URL] or [login to view URL] They can then display these items on their animals' pages and create stunning sceneries. Examples: [login to view URL] [login to view URL] [login to view URL] etc We want to add additional items in this shop so that players can have even more fun! We've purchased a few pictures on various websites (these source files are attached to the project), now we need to prepare them with the proper names and dimensions. You have to crop & resize the pictures, but you must never change the width/height ratio of the pictures. For each item, you must deliver 3 transparent PNG files (compression ratio: 1): A/ a "source" picture (original file) Filename: [login to view URL] (where XXX must be replaced with the item's ID) B/ a "standard" picture Filename: [login to view URL] (where XXX must be replaced with the item's ID) Dimensions: up to 330x250px. The width must reach 330px and/or the height must reach 250px. The item needs be horizontally and vertically centered in the picture. C/ a thumbnail picture. Fixed dimensions: 60x60. Add horizontal or vertical size if needed The item needs be horizontally and vertically centered in the picture.
