I want do design a simple network game (like tic-tac-toe,or checkers) on linux and looking for somr graphics tools which could be used to render simple 2D graphics along with some network programming. I am good at java programing but i dont know how to handle images etc in java and render graphics. i know netork programming in java and c.
please help out about how should i approach a solution to the problem.

Game Scenario: (although it sounds childish, it will make someone drill down to his basics.)

1) 2 player network game.
2) one player uploads an image from his hard disk and rotates it and sends to another user
3) other player over the network corrects the orientation of this image and sends it back to the first player.
4) the first player declares the second a winner or loser.

probubly better to have all the resources (images, sound, etc) on both computers
so all you have to net acorss the network are instructions
i have no network experence but some game experence but your question isnt clear

just figured your post out
you can just send the image over a sockit stream but it may take a while
seems like a crazy idea 2 me

Send the original image to both players, then only send the manipulation data on any future updates. IE: Player 1 uploads picture, picture is sent to Player 2. Player 1 rotates the picture then sends only the transformation (rotation/scale/translate) matrix to player 2, player 2 takes this transformation matrix and applies it to the image on his screen. Player 2 then makes his changes and the new transformation matrix is sent to player 1. NOTE: You will have to make sure the player who is waiting for the other player cannot manipulate the image.

The only time you should be sending the image over the network is on first load/upload of a new image.

As for the technology just use SDL for this, unless you want to do advanced manipulations to the image (IE: GIMP/Photoshop) then use OpenGL.
