Texture memory

Hello! I want to understand how texture memory works. I tried to download bunch of files (426 x 249). Each file is about 15kb. Then I run an r2d2_bitmaps command via telnet. And I found something, I couldn't understand. Why each image tooks so much memory (about 0.45mb). And there is one question, what is these files:
