Probably not in any reliable commercial sense. The main theme from the answers is that while 5MP can be enough for some uses, a 2001 compact camera’s overall image quality and usability are the bigger problem: noise, limited ISO/aperture control, hot pixels, no RAW, and older sensor/lens/screen performance make it hard to compete for stock or other quality-sensitive markets.

Stock photography is difficult even with modern gear, so using a camera this old puts you at a strong disadvantage. Artistic or heavily processed work may still be possible if that suits your skills and style, but that’s more about artistic ability and finding an audience than about the camera itself.

So yes, you may still make images people enjoy, but if your goal is to earn money consistently, the practical advice is to upgrade rather than try to force an outdated camera into markets with technical requirements. Even entry-level newer cameras can deliver much better results and are likely to be more enjoyable to use.
