i used WinHTTrack to download a webpage with a ton of pictures that i wanted. for some reason it saved them all as html files. when i rename them to jpg they work fine, but there are too many to do them one at a time. so i am wondering if there is a way to rename all the files in the folder, or change all the file extensions in a folder.
here is the web page, so you can understand why i cant rename them one at a time.
