I have checked out the various suggestions made and followed a number of leads of my own, asked questions and had some replies. Dave suggested checking out Rapidweaver, a programme on the Mac for website development.
I checked out their site and was immediately attracted by the statement that it could be easily updated without republishing all the files - a flaw with many simpler publishing programmes and templates. When you have 300 images - uploading can take 24 hours!
I found a link to a couple of web videos, one their own and the other by screencastsonline.
Current status is that I have purchased this very inexpensive software, along with a couple of plugins and have been able in minutes to make the beginnings of a site, with ideas on how I'll do the whole thing, even including my blog if I want. I still can't get the uploading feature to work (wrong settings somewhere) so export it and upload it with Fetch, but it works. This weekend I'll have a real go at creating the site.
If curious, you can follow my progress here
Is this my final decision? No, I could easily decide part way through that it isn't right for me, but I think it will be alot better than staring at an empty Dreamweaver screen with little idea of what I want or how to get there.
These tutorials and reviews and so on on screencasts . They pertain to macs only but after years of being the poor relation, it doesn't hurt to be top dog for a change. There may well be pc programmes that are similar but of course are no use to me so I don't study the market.
I have discovered one problem already, other pages don't show up - they do if you roll the mouse over them but otherwise not - perhaps black on black - will have to check when I get home tonight.
