They look like hot-pixels..

Basically some pixels on the sensor can 'lock' when the camera is used a lot, and especially on long exposures ( like your night shot )..

Two techniques are used to clean this. The first is an in-camera thing and I don not know if the E-500 has it. It's called dark-frame subtraction. You don't really need to know how this works, but you can look it up if you want..

The second is to try not having the camera on for too long a period. What "too long is" I don't know and no-one does, I'd say..

This is quite common..

You copy the "url" from your host site, right click on a photo, click on properties, it starts with "http, and ends with jpg "then just past it into this page, then when the page is opened it is there.

Olympus builds this facility into the camera menu so it may be performed by the user rather than a service center..

The pixel-mapping function is found in setup menu no.2. This should sort out any hot pixels..

If by odd spots you mean the occasional red, blue or green pixel in the picture. Then dark frame subtraction will remove them..

As someone suggested you can map your pixels, but this only maps out dead pixels and those pixels probably aren't dead, just hot. You can't hurt the camera mapping the pixels so go ahead. I just don't think that it'll help..

Now on the other hand if you mean the diagonal streaks over on the left side of the picture. Those are probably internal lens reflections off the apature blades.A member of the rabble in good standing...
