I have been working with Unity3D for awhile now, but just noticed that a majority of the demos use TGAs for their images. I have been precompressing the images using Photoshop (WebSafe) to keep the size down. Does Unity do an equally good job, or if by me using my method Unity is compressing it further and thusly reducing image size further than it needs to be? Thanks!

Unity does a better job than TGA, it uses LZMA to compress assets.
Generally though you need to keep in mind that they are only that small while they are not loaded. In the RAM anything but hardware compressed image formats have the size of BMP

Compressing images yourself is worse than useless, because the only thing that matters in the final build is the texture compression settings in Unity. Since you’re using Photoshop, you should keep images in Photoshop format for ease of use (layers, etc.).
