OK then it just sounds like the file size is to big then.I had the same problems when I started.There are a few ways to solve this problem.One is by using paint then selecting resize.I have in the past taken it from 100% to 20% it then is a good size and knocks the file in half.You could take it down even further here is the same photo resized at a different percentage.
This top one was resized at 15%.Took the file size from 1.13MB to 159KB.You may not need to go that small.
This one I did at 40%.File size from 1.13MB to 625KB.So that one is properly the better size.Once you have the size then just save as JPEG.Then you should be able to upload your picture with no problems.
When I do multiple pictures I use my e-mail program as it can resize really quickly,much quicker than paint can.
There other programs out there that can do it,but I won't confuse you with them as they all have a different ways of doing it.The simplest program sometimes (As is this case) are the easiest and the best way to go.
Give that a go see how you go with that.
Also if your going to dismantle the auto drive I'd like to put my hand up so some bits.
Just so you know the sticker on the engine doesn't give you the mark number they are merely the mark number of the engine.
This is the order the auto drives go in.
VC-160 Auto Drive Mark I
VC-160 Auto Drive Mark II
VC-160 Auto Drive Mark III
VC-160 Auto Drive Mark VI
You can see the handles here.My mark III isn't complete and doesn't have an air tube or filter box.It should be like the IV on the right.
