Download the file for your version of Joomla from my downloads page.
For the 1.5 version you need to follow these instructions - (the instructions for the 1.6 version are similar, but I never got around to writing them - email me if you are desperate for pointers)
In the administration page - click on Extensions then Install/Uninstall
Browse to where you saved the file you downloaded and upload it to your website
If everything goes to plan then you should see something like the screenshot below :)
(most of the images are from my original website www.givemeajobsoicanmovetocanada.co.uk - hence the logo)
Now click Extensions then Module Manager to setup the module to work with your website.
On the dropdown, look for the module - its called mod_custom_transparent_gtalk_status click it when you found it!
Click on the module name to edit the settings and get it looking luvverly on your own wonderful webpages.
As is my usual approach, I'm not going to explain how to choose the position of your module or which pages that you want my module to appear on, the Joomla! documentation is pretty good for this, or you can always do what I do - press stuff until it works or vanishes ... if it vanishes, go for a walk and think about what you have done!
How to adjust parameters for the module ...
Module Class Suffix - just the standard way of adding individual styling
Basic Styling - Position everything to the Left - Right or Centre (yes I spell it correctly LOL)
Add some text before your status image - you can put HTML here if you want :)
Add some text after your status image - deja vu ? but after rather than before ...
Show the Badge Title - when you setup the Badge through your Google Account - there is an option to have a Title for your Google Talk (Gtalk) Badge, this option allows it to be shown :)
Show Message - This shows any custom message you might have for your Google Talk - or it shows which music track that you are listening to ... this only works with Winamp, Windows Media Player and another one that I don't have :)
Custom Message Override - Once I'd built this I realised that if you have an image that tells you what your online status is, you don't really need to show this in text form, so this allows you to turn the test status on or off ...
Token from your Google Talk Badge - when you setup your Google Talk Badge, there is some nice code that you need to copy and paste into your webpage for the chat facility to work ...
you'll need to select the bit between tk= and & - this will be a really long string of characters and numbers ... (don't use mine, otherwise all your friends will be chatting to me and will obviously no longer find you interesting enough to associate with).
Oh, don't forget to choose Standard when you setup your badge in your Google Account (did I mention that? probably not ... do you have any idea how long these tutorials take to write? its a total pain ... its not like I don't have anything better to do ... if you like the module, make a donation ... any amount ... nothing too small) ...
... Its been a while since I wrote the module, but I'm pretty sure I didn't test it with any other of the choices ...
Save your settings and navigate over to see if everything has worked out ok ...
This is the result with a custom message ...
Which Music Track I'm listening to !
Not to worry, I've included a few more generic images for your guys (if you want mine email me, though it would seem like an odd request and I would probably have to report you for being strange)...
If you want to use your own images, you'll need to use cPanel or ftp your images to /modules/mod_custom_transparent_gtalk_status/images/
There are 4 images for Google Talk status - online.png, offline.png, away.png and busy.png ...
... ignore the logo.png (thats just for me).
Good Luck -
Show Google talk status on your website - a great resource - showed me how to use cURL to get the info I needed
gtalk status checker with php - really helpful in breaking down the string returned (eventually used a different system)
parse a string between two strings in php - brilliant little piece of code I used to find the info I need from the string returned from Google
