Adding Many Saved Images in Android App

The application I'm trying to build will have a lot of images displayed (in ImageViews), and I'm not fetching them from a server/online service as it will need to be used offline. I know I can just dump them in the res/drawable directories, but I was wondering if there's any way to optimize this. Is there a way to somehow compress these images (besides making them smaller, they're already as small as I need) or use some other sort of android tool to better store them locally on the device?

I could just be overlooking a well used feature, and if so, it'd be great if someone could point me to that.

Edit: If I were to compress the images somehow, I would need to decompress at runtime or something, and that would take another thread/loading time. I'm not sure how to do that either, so I'm just brainstorming various ways, and I thought someone here would've come across this at some point.

If you haven't already, this is a good read - http://developer.android.com/guide/practices/ui_guidelines/icon_design.html#design-tips

When saving image assets, remove unnecessary metadata

Although the Android SDK tools will automatically compress PNGs when packaging application resources into the application binary, a good practice is to remove unnecessary headers and metadata from your PNG assets. Tools such as OptiPNG or Pngcrush can ensure that this metadata is removed and that your image asset file sizes are optimized.

Outside of all other compression logic the above would be the place to start. Also when you say "optimize" - do you mean optimize the way images/drawables are loaded in your app or just the amount of space (on disk) the app will consume?
