I think I have bitten off more than I can chew ...
I know what I want to do, and have done it in the past, and here is proof:
I once wrote a site in html where I set up (using php) one pro-forma page of images of Bury St Edmunds, and depending on a parameter that I passed it, so the page displayed images from a different category, for example, "streets", or "houses". This was easily set up because I had a MySQL database with all the data I needed, not least being a field with the category to which an image belonged. So, the process of "select where category="house" was dead simple. Well, at least I understood it! If you look at
www.burypastandpresent.org.uk/jarman-ima...s/moreton-hall.shtml you will get the general drift ...
Now for my Joomla problem:
Thinking that to do a similar in Joomla would be easy, I have undertaken a website where I need to do a similar exercise. Yes, it is different, but once I get the hang of passing a parameter to "whatever" and then getting "whatever" to accept the parameter and act on it, I should be OK. Thing is, I don't know what "whatever" is! So, ignorance is my problem!
Please can you point me in the right direction?

Chris
