About PhotoQt

PhotoQt is an image viewer that does things a little different. Its unique interface might remind some of the 'Lightbox' image viewer that can be found on some websites. Others might be reminded of smartphone image viewers. In the end, there are certainly similarities, however, PhotoQt is written and optimised for normal desktop usage. As such, the main interface consists of nothing but the viewed image, with a few elements available as fade-in/slide-in (e.g., thumbnails along the bottom edge). It might be a little odd at first to use, but I believe its speed and flexibility allows it to adapt perfectly to each individual workflow.

I started developing PhotoQt during the second year of my undergraduate degree. Since then it has been an ongoing hobby of mine, spending many hours of my free time working on it. Looking at some of the older versions (if you're curious, here you can check out all of the older versions) PhotoQt has come a long way since it's birth about 5 years ago... and I'm long not done with it!

About Me

I am Lukas Spies, the sole developer of PhotoQt. Born and raised in the southwest of Germany, I left my home country for university shortly after finishing school. Since then I have live for some years in Ireland, Canada, USA, and France, studying and doing research in Mathematics and Scientific Computing. I started playing around with programming since I was about 15 years old. So most of my programming knowledge is self-taught through books and websites. The past few years of my studies I also did a lot of programming as part of my research. Through all of that I gained a good bit of experience in programming using different programming languages.


There have been (and there will be) times where there seems to be very little to no development happening for a few weeks. This typically happens whenever life gets very busy for me. These dry periods, however, typically don't last very long. So don't panic if you see that happening, it doesn't mean I have abandoned PhotoQt!

Ultimate Goal

If there's one thing I want to achieve with PhotoQt, then it is, that you find it useful. But developing something like PhotoQt takes up quite a bit of my time. If you like PhotoQt, and if you're able to, I'd be really happy if you could spare a Euro/Dollar/... or two to show appreciation for this little application of mine. Thanks a million :-)

Thanks to everybody who's helping with a translation or spreads the word about PhotoQt. This project could not exist without all of you!
