Hi,
Since what is out there does not really fit my needs or is to complicated I made a very simple AIR application to deal with Atlas Textures.

Basically it loads you pngs into one png and also provides the .h file which can be included into the project.
-emc
p.s. how do you use the markup ? like html ?
any 2^N size:
256x256, 512x256, 512x512, 1024x512.
iphone 3GS supports 2048x2048 textures (not yet supported by cocos2d).
Hey, nice one. I just tried it on a Mac and it works really great.

I checked now under OSX and Windows XP and both work for me.
I just updated and renamed the button so its more clear what it does. I also excluded the atlas.png from being included into the Atlas Texture.
I will see if I add a mode to manually include/exclude images before creating the atlas texture.
@eemceebee: Thanks for your contribution.
Note that zwoptex, which I still prefer, can be downloaded if you absolutely need a local copy. The author discourages this so he can have some idea how people are using it, which is very fair. But if you must, in Safari you can File | Save as... and create a web archive that works offline.
The main reason I prefer zwoptex is that it generates XML instead of a .h file, which means we can load everything dynamically.
eemceebee, would you consider adding support for XML saving/loading?

I am currently working on a new version, where I could also add xml saving option. I will not care about loading, because I really do not want to care about placing anything manually on the map. I think the lightmap algorithm is perfect for this and the optimum for placing the single images on the map.
However, the main reason for the new version is a feature I call smartCrop. If I save my icons, I sometimes have borders with transparent pixels which are a waste of space. Maybe it is just me being lazy cutting them in the first place, but I think its a work saver.
@eemceebee
For loading, I actually meant loading the saved XML file and atlas map into your cocos2d app, not loading XML back into the tool. I agree that it's best to just rely on the algorithm!
The smartCrop feature sounds helpful. zwoptex crops your images too, but importantly, it remembers offsets for where the images were cropped. This is really important when you have layered animations that need to align properly when you load them! In this case, the images you import often have transparency around them, but this is on purpose so they line up with other layers.
By the way, if you use Photoshop, you can use Image | Trim... to easily remove all transparent pixels from the edge of your icons!
