I have seen reference to XAMPP or WAMP here on the forum but have no idea what that is so no, I am not using that, just do frequent save, backup, ftp and check out on the different browsers. That is one reason I want to use DW to make that process a bit less onerous.I presume you are testing it on a home based server first (XAMPP or WAMP) which would make it a lot easier to test and try things out.
Even try it without the height=1700 code - it *should* dynamically size itself without it.
On the length, I had found that unless I kept lengthening it I would be missing some images or parts of images.
As I am adding and modifying I am seeing and learning about what the code actually does but still a looong way from getting any good grasp in understanding much of it. I admire those of you to whom it just seems to be so simple, but then I've come a long way as well from when I first started to get into the code.
