Yes, you have to have the app installed to download images and vidyas. Otherwise take a screen grab from the browser. There are ways to get that image, but you’d have to look in the browser console to get it. There is no way to put images on FR without remote hosting or hot linking. FR cannot afford to host all the images people would post.
PS. In Windows if you want to take a screen grab hit Windows Key + Shift + S at the same time and you’ll get the cursor to draw a square around what you want captured.
