HowTo: My journey through self-hosted photo gallery approaches

Quite soon after creating this blog I found that it is also the perfect place to present selections of my photographs.

During that time I was already using Adobe Lightroom. If I remember correctly it was still version 1.X, but it already had a convenient one-click solution to create web-based galleries out of a collection of photos. So I could easily create one and upload the resulting folder to my webserver. I even was able to customize the generated configuration file in order to modify the title and description of the Flash-based gallery player. And here comes the downside. It was based on Shockwave/Macromedia/Adobe Flash, a nightmare regarding security and stability.

As soon as one is familiar with the basic concepts and techniques it will be nothing more than locking/unlocking your front door. And probably you did not yet remove your door lock for reasons of simplicity?

HowTo: Linking within the Flash Web Gallery of Lightroom

Adobe Lightroom

As image processing and management software I am using Adobe Photoshop Lightroom (meanwhile in version 2.4, still looking for an adequate Open Source alternative).

One thing I like about Lightroom is the easy, fast and integrated way to create web galleries out of your photo collections. What I was missing so far was a way to link back from a certain flash web gallery to my gallery overview and to the main page of my blog.
