How can I change the default order of My Pictures?

I can change it to sort by details, newest date on top (the only way I use it) when I bring it up directly.
But whenever I reference from with a program or web page (usually to select a picture to attach or uplad), it always appears in big icon format, sorted oldest first. So, for each and every file I attach or upload I have to repeat these steps: Change View to Details. Sort by date (gives me oldest first). And sort by date again (for newest on top).

This aggavates me several times a day. Is there a Regedit way to fix the default order?

I’m on XP, upgraded to current service packs.
