if trying to post already existing photos, go to your pictures folder, double click on the photo you want...this will open the photo INSIDE your default photo editor....look for the button or menu item called 'resize'.... once you get inside that button, there will be something showing the actual size of the photo and a way to make smaller.... go downward in size till it is less than 2 MB in both directions... save...File, Save or File, Save As... make sure you note the new name so you can find it when uploading to the QB....
