How do I use these downloaded free web templates in Dreamweaver?
OK. You sound like you are struggling a bit. If this is totally new to you then Dreamweaver is probably not the best programme to use. Yes it is very good but in all truth the developers take it for granted that you already have a fair bit of knowledge of web design programmes. You should try something a little simpler like front page express from the dreaded Microsoft. That will more than suffice if all you are looking to do is create a smart looking website. There are even more simple ones around like word server. If you are looking to do an E-Commerce site then it is worth paying a bit more money and using Actinic. It is very good and can be as easy or complicated as you want to make it.
