to change the logo size just change the distro_text_size on line 13 to a greater number. Changing the 1 to a 2 will make the object twice as large.

chengelog:

Changed line 53 from:
startup_sprite.SetX (screen_width / 6 - ImageGetWidth(startup_image) / 2);
to:
startup_sprite.SetX (screen_width / 15);

Changed line 62 from:
shutdown_sprite.SetX (screen_width / 6 - ImageGetWidth(shutdown_image) / 2);
to:
shutdown_sprite.SetX (screen_width / 15);

Changed line 79 from:
SpriteSetX (mint_sprite, SpriteWindowGetWidth() / 6 - ImageGetWidth(frame_image[int_frame_index]) / 2);
to:
SpriteSetX (mint_sprite, SpriteWindowGetWidth() / 15);

Now the object will always be on the screen near the left edge.

You can use other values instead of 15. Larger values will place it closer to the left edge.
