You are right I've tested it with a 1MB gif and it wasn't stored.

My multiple page upload now stores the pics with a random number and
after the second page moves it to the right location and name.

so I implement the functionality in my app that was provided by helma
before 1.6.0 final. So the deletion of tmp files has shifted to the app.

I think its a good idea to "free" the memory from big files and delete
them after a request so +1 for that.

I should keep an eye on this when developing new apps.

Thanx again to clear things up.
