Hey vincent3569, I also tested Piwigo, a few years ago, have invested a lot of time, and then it was all lost time. But I do not remember what was so terrible about it.
One year before Gallery3 went into hibernation I switched from a pure HTML Gallery to Gallery3. I had tried some photo CMS and Gallery3 was the best because of its simple structure and many useful features. The message from the end of Gallery3 was a shock to me. I had invested a lot of time.
Why do I want to leave Gallery3? Because I think about the future. Gallery3 has no support, except in a Yahoo group. Gallery3 / Menalto has no future. I am not so flexible and do not have so much time to switch to another CMS at any moment. I've been trying for a long time to test Zenphoto again and try to make some adjustments.
The file structure is very good. Also the recognition of the files. But, I do not publish immediately at detection, because then still title and description is missing. At Menalto, the tree structure is even more consistent, with cleavage in resize and thumbs. That is very convenient. Always bad is a dump (and rename). Order must be.
I still have a little problem. I first upload the photos to a editing folder. There I add title and description, maybe even sorting. Then I move the photos to their final place. It is not so good that in Zenpghoto the resize and thumbs are not moved.
You misunderstand me. I do not want to complain. I program myself and make everything freely available. It is rarely thanked. Everyone wants to have everything for free. But I do it because I enjoy programming. My gallery is also freely accessible and many elaborate collected information is published in it. Partly very detailed descriptions with thousands of characters. I am a historian, by the way.
You understand me wrong even with Zenphoto. I do not want you to change Zenphoto. I want to customize Zenphoto for me. I do not agree with everything in Zenphoto. But I do not have to take Zenphoto as it is, because I can adapt it to my needs. Core hacks is such a bad word. Better would be modding!
It would be nice of you to get support by modding. You know your software best and know where what is. I do not like stiff software like a rock. But, if I do not like something, then I'll say it out!
