I can't get an answer to this one elsewhere so here goes !

I run a sports blog on game nights that needs to have a simple widget or plug-in that carries the game score and which updates without visitors/fans having to continually hit F5/Refresh in case the score has changed (that screws the site up big time !). A simple text widget would do.

There is other content on the page - eg: a chat room - so I don't want the whole page to refresh - only the score.

It sounds simple but I just can't find a way to do it and would love some ideas !

The only way I can think it might work would be to have a jscript that did it

I'm looking at using the header image as my scoreboard by uploading an image that I update with the score.

I'm thinking if I place only one image in the theme's images/header directory (with the scoreboard on) and select the option to rotate every 15 seconds with javascript then each time I upload a revised scoreboard image, it will pick that up on refresh.

Will that work - I can't see why it wouldn't ?

Readers browsers will cache the first image it loads. I dont think it will work, they will only see original image loaded when they first viewed that page.

it should be easy to test, let us know if it works.

A quick search on wordpress.org found this plugin.
