You're offtopic.
You also don't seem to know anything about GDD's.
And I haven't made any mistakes.
And you're a bit out-of-line. I assure you that Mr. Petrie is far more familiar with GDDs than you. You don't think you've made any mistakes because you don't know enough to see them.
You're here asking rather simple questions that any amount of cursory research would answer, so either you haven't bothered to do your own homework, or you'd sooner let the opinions of internet strangers, however well-intentioned, set your course. Neither of these inspires confidence that you're willing or able to consider all the angles. The fact that you so readily dismiss an opposing viewpoint reinforces that lack of confidence.
Anyone who's designed anything much more complex than doorstop knows that design has to be iterated upon. As they say in war, even the best-laid plans don't survive contact with the battlefield. All that Josh was saying is that you're front-loading too much design with too little hands-on experience. the more experience you have, the more you'll be able to pre-design to a reasonable facsimile of the end result. This is true of design for both gameplay and technical implementation, and more-so where they touch. If you spend time laying out a poor plan, the best outcome is that you'll throw away the plan, but the worse (and more likely) outcome is that you'll throw away the plan, and also sink a lot more time into correcting the problem, and all the systems that were built around it.
The trick to planning isn't laying out all the details ahead of time, it's knowing what details should be laid out, and which are best to discover along the way. Image formats, while important, are absolute minutia. Choosing a resolution can be important, but a better question would be, "can I, and how do I, support different screen resolutions and geometries (4:3, 16:10, and 16:9 are most common)

I don't agree.
The pre-development phase is free since I'm the one doing it.
The more important details I can include in the GDD that I give out to the team later the smoother and faster development will be = cost less money.
So It's just much smarter if I already know what sizes the images should be and even have them ready = saves lots of time because the programmer can just puzzle the pieces together instead of discussing and planning with me = cost more money.
And I really wasn't out of line, The moderator succesfully have derailed this thread now.. Good job on him.
He didn't even leave any comment at all about what the thread actually was for... images.
