GIMP is an open-source image editing and manipulation alternative to Adobe's Photoshop. GIMP includes features similar to those in Photoshop and provides an affordable way for photographer's and graphic designers to edit images and create designs. One of these features is the ability to create selections and paths. Paths can be added, edited or removed through the Path's Dockable Dialog.
Open the "Paths" dialog by clicking "Image," "Windows," "Dockable Dialogs," then "Paths."
Select the Path that you want to delete or remove.
Right-click on the path and click "Delete Path" from the context menu or click the trash can button in the lower right corner of the Paths window.
