Hi,

I've written a python script that reads some data from a file and generates a
.png image. I want to have a button on my MIDAS status page that:

- executes the script and waits for it to finish,
- then displays the image

How can I do that? I tried using the sequencer to just execute the script every
30 seconds, but I can't get it to work, and it would be better to only execute
the script on demand anyway. 

I also am having trouble getting image display to work. I have the ODB keys set:

[local:oven1:S]/Custom>ls
Temperature Map&                /home/deap/ovendaq/online/index.html
Images

[local:oven1:S]/Custom>ls Images/temps.png/           
Background                      /home/deap/ovendaq/online/temps.png

And the HTML file is just this:
<img src="temps.png">

But the image won't display. It shows a "broken" picture, and when I try to view
it directly it says: Invalid custom page: Page not found in ODB.

Any help would be appreciated...

Thanks
Shaun
