for e-bay even the largest picture is small 640.480 is ample
at that resolution pixels don't mean a thing ... 3Mp will print up to a4 .... 6 to a3 .... 12 will wallpaper an elephant
(mine is bigger than ....) ....
a big pixel count will actually reduce the resolution quality if the end result is small
remember if you can see every scratch .... well .... you can see every scratch ... and why would I buy from you if it's scratched?
your phone will just about do the job .... concentrate on even lighting + a plain background. use diffusers (4 or so layers of greasproof paper)
the lights need to be white at least 150 watts each
2 just below level, and at 120 - 90deg to the subject (camera bisects the angle ) .... 1 lamp high and just in front of the camera ... but out of line.
this should give a soft even light that will wash the detail to give a clear but not over detailed shot
you can make something like this out of old white shirts
