Regarding attaching pictures - make sure you resize them down so that they're not over the limit (which is around 600K IIUC).
It would be really helpful to see your problem.
Sometime the first layer is a bit bigger because the slicing software is configured to extrude more plastic initially to get better adhesion to the bed. As an experiment, you can try printing with a raft, and see if the problem is now with the raft layers, and not the model layers.
