I recommend saving any images you want and uploading them to your own site because I might rearrange things and break links

Save every image on a page really fast:
Firefox: right click (not on an image or text), "Save Page As..." save as "Web page, complete." It will save a .html file you can delete plus a folder with all the images that were on the page.
Chrome: right click, "Save As..." save as "Webpage, Complete." It will also save .css and .js files in the folder and you can delete those too
