Saving Your Image

Blender will tell you when you have made changes to an image that you haven’t yet saved. If you look at the UV/Image Editor header, the Image menu will show an asterisk (*) that indicates there are unsaved changes. Open the Image menu and you’ll see the save options. Also, pressing Alt + S inside the UV/Image Editor will save the image. Pressing F3 will perform a Save as... for the image.
