The chain isn't a lock it is a link. The layers are linked together so that moving one of the linked layers will move the other as well.

Hi!

Is there an easy way to lock one or more layers, so that one cannot move or change them by any other way? I thought that was the function of the little chain icons in the layer windows, but they seem to do nothing... By the way, what are they for?

Thanks, Victor Domingos

They're used to move several layers at time - they keep same position. Usefull tool, when you wish to move several layers and do not want their composition to change. Otherwise you ougth to merge them what is not always what you want to do.
You change active layer by selecting one in Layers tab. You select it and all actions you do apply to active layer only.

In addition, if you click the linking icon in the paths or channels dialog, the same function is performed, not just with each individual image element (i.e. layers, paths, channels), but across them as well. If you have the link icon clicked for a layer, and click it for a path or channel, then move the layer, the path or channel will move in sync with the layer (or move the channel/path and the layer moves, etc.). Kinda handy. If you make a selection, then save it to a channel, then later say, bucket fill the selection, then decide to move the layer you just bucket filled, if you have the channel and the layer linked, you can move both, then if you need to recall the selection for some reason, it is in perfect registration with the bucket filled layer.

Everything is linked. There is no way to make specific links. The only way I can see to do it, would be to link just the channel and layer in question and nothing else.

Hm.. interesting. And how do I tell GIMP wich channel should be linked to each layer? The link icon gives no info about what is being linked, right?
