Clipping & Resizing 27 user created dog pictures to add them to an online dog game

We run a few online games dedicated to animal lovers, among others our dog game Dogzer, available in 5 languages. On this game, players can submit dogs pictures they've created, in order to have them added to the game. We've attached some user submitted pictures that have been approved and that we want to add to the game. For each picture, you have to clip & resize it and provide 2 files: 1/ One PNG source file ([login to view URL]): no size limit 2/ One 330x300px PNG file ([login to view URL]) 3/ One 115x105 GIF thumbnail ([login to view URL]) All of them must be transparent. In each picture, the dog needs be horizontally and vertically centered. For example, if we provide a file named [login to view URL], you have to prepare a directory named 1340000312, with a subdirectory named "2", which has 3 files: 1/ [login to view URL] 2/ [login to view URL] 3/ [login to view URL] ---> see attached example Never twist the pictures created by user. The width / height ratio must be the same. If there is a shadow in the source file, please remove it. We will have more similar projects in the coming weeks & months. PS: the file attached contains 20 of the 27 pictures. 7 are still WIP and will be added afterwards.
