First of all, I want to thank you for uploading all those great quality images on the site, they're simply amazing.
I also wanted to ask you that, if possible, instead of just uploading new sets of images, please use the "Replace" option for each image; that way, if the old images were already being used on other pages, your new images will take their place and automatically appear in all those pages without us having to do it manually one by one.
To replace an image, got to the old image's file page and from the [EDIT] button's dropdown menu select "Replace". You'll be taken to an 'Upload photo' page where you can browse and upload your new file. Now your new image will appear in all those pages the old one was being used on.
