Okay, so I tried to download a pic
select the file , choose Open With - Microsoft office Picture Manager. Choose compress file, choose web page size. This lowers the resolution. if you need to make it dimensionally smaller to fit nice on a page choose resize and change the dimensions... make sure you still change the resolution because that is where the issue is. Make sure to save as - not just save or you will ruin your original. Then after you save as when you close out do not accept the changes to the original...
