Web browser differences
It's highly recommended to use either Google Chrome or Mozilla FireFox as your web browser, as Internet Explorer doesn't support some features such as inserting multiple images at once, or resizing images whilst maintaining their proportions.
Google Chrome and Mozilla FireFox are also generally faster, more secure browsers, so I'd highly recommend using one instead of Internet Explorer for your everyday browsing as well.
