I use a variety of editors to create/debug jAlbum skins. Mainly I use three -- Homesite, Textpad and Selida.
Homesite - http://www.macromedia.com/software/homesite/
The version I use was a free one that came with a Computer Magazine (4.5). It's now at version 5 and part of Macromedia's Dreamweaver package. Homesite has a lot of features (like auto completeion of tag attributes) that make it very easy to use to edit code with. The drawbacks are that it's NOT free and it also takes up a lot of system resources.
TextPad - http://www.textpad.com/index.html
This is a neat little shareware text editor. You have tag colouring, but you can also have a variety of syntax definition sets, so you can also include jAlbum tags as well (I never quite succeeded in doing that with HomeSite). It's also a good editor for non-coding text files, and there is a plethora of add-ons and also ones related to JAVA editing and compiling.
Well, I mainly use two editors - Visual Studio.NET and UltraEdit
Visual Studio.NET - http://msdn.microsoft.com/vstudio/
This is Microsofts integrated development environment with support for VB.NET, C#, C++, ASP and much more. It has code completion, intellisense, syntax highlighting and the most complete set of context sensitive help documents available. The only drawback is that it is far from free...
UltraEdit - http://www.ultraedit.com/
This is in my opinion the most versatile text editor out there. It has syntax highlighting for ALL languages (400 when I last checked), a nice regular expresison based search function and can work with files of different byte order and character sets. You can compare it to Emacs only user friendly... It has a reasonable price as well, $30 I think.
Allaire? The same company that makes (made?) Cold Fusion? That was a nice web language once they upgraded to 2.0.
I usually use NoteTab Light, I have personally found it the best among the free, light editors out there (and I have tried a few, some listed in this thread). But I guess this is down to personal taste... it has some very nice features like remembering which files were open and automatically opening them on startup.
For checking out a large number of pictures quickly (like after a hard day of shooting them), I haven't found a truly satisfactory viewer yet, but Vallen JPegger is pretty good. I must have tried most free ones on Tucows by now...
For editing EXIF/JPG data I use Exifer, like most, I guess. For editing pictures, there really is only one alternative, PhotoShop.
And finally, I use Mozilla Firebird or Opera as my web browser (except for the few times I have to use IE because the site creator is retarted). I used Opera exclusively up to very recently, but for some reason version 6 started crashing on both my home and office machine and 7 is in my opinion, not as good as 6. Prettier yes, but not as slick.
Please note Firebird is still beta. Works well enough for me. There are a few minor bugs, but nothing serious. The full Mozilla is bigger, slower, has lots more stuff and AFAIK, less bugs: www.mozilla.org .
LOTS of plug-ins available, and I particularly like the built-in online validation checking.
customizable keyword help and keyboard shortcuts;
multiple methods of previewing;
a spelling checker and a thesaurus;
automatic detection of and integration with third-party applications, such as style editors.\
write your own plug-ins
