For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
Viewing images held in a MySQL database via PHP

LOTS of questions on this at the moment. We have a couple of sample scripts that do it - have a look at:

* feeder.php which adds images into a database if they've been uploaded as plain text files, displays them from the database if that's where they are already, and generates a rather more informative than usual graphic if you call up a picture that does not exist.

* pic_alog.php which selects images by title from a database. There's a page here which explains this a bit more, and points you at the upload script too.
