To shrink the photo to fewer pixels in Photoshop Elements, use Image->Resize->Image Size, then check the box Resample Image then change the Pixel width to 1000 (or X). The height adjusts automatically because Constrain Proportions is checked by default. Changing the pixel size is not available until you check Resample Image.
In the feature photo and in the one below, all the Photoshop Elements auto processes from the Enhance menu were applied except Auto Red Eye Fix.
