Question I Need Some Contacam Help....

How can I get contacam to save snapshots all with the same filename? And control the time interval?

So that every so often at my discretion, say every 1 minute, I'll get a saved snapshot.
One minute later another will overwrite it.
One minute again, another overwrite...

It is currently doing a great job when I ask it to of saving snapshots each with a timestamp to change the name and thus allow filling the dir with hundreds of images.

Not what I want. I'm trying to sort of 'stream' pics to a web page but instead of streaming and all that bandwidth just send periodic stillshots.

I don't see much mention of Contacam in these forums. And I couldn't google a dedicated forum. If anyone knows of a better venue for my questions please let me know..
