There's a specific command for that under 'layers'.
You can also do it in the layers "toolbox" (wrong term- but the stuff on the right side of the screen)
Press control + L to open the Layers window.
Click on windows / dockable dialogs / layers channels paths
In the "Layers, Channels, etc" window, right click on a layer and click delete.
Press Control + L to re-open the Layers window
IF your picture has multiple layers (it may not - jpeg's don't when brought in) it will allow you to determine which layer is being modified by the editor, and to rearrange which layers are on top.
Unfortunately, the only formats that preserve layers in GIMP is .xcf (the default format.) If you're looking to upload an image online, or use the image for anything outside of GIMP, you have to export the file by clicking File>>>Save As>>>(specify format in drop box)
The dialogs in GIMP are windows that contain tools and options that you can use to change your image. All dialogs can be found by going to windows > dockable dialogs. The layers dialog, for example, allows you to view all of the layers in one box and enables you to change the mode and capacity of each layer, along with other options.
can you save as .psd?if you can then do it and send
You open up the pic and then click the layer button and then click add layer and the layer box will come up.
You can start Gimp by going to All Programs and selecting Gimp
