I am new to Mac and having difficulty changing names in Finder. I know that I can select the file and go to "Get Info" and change the name under "Name and Extention". However with hundreds of photos, how can I change the name of multiple photos at once and just assign a different number after the identical name? I ask because when I take digital photos, the camera assigns the same name to them: i.e., dsc_00007.jpg. When I try to download my pictures to a memory card for use in a digital frame, it will not download many of them because they have the same name and wants to replace it. I need to rename them under "Finder" so that I can download ALL the pics without the system thinking that they are duplicates. Any help would be greatly appreciated. Thank you.
