Once upon a time, a normal person could go onto google and, with a few clicks, could find amazing hi-resolution images. Google also gave you the option as to the royalty status of the images. Sometimes images are rights protected, other times there are catches, but then sometimes...ohhh yes, with some images you can do whatever the (bleep) you want.
So if you combine completely royaltly free images with high resolution, there were a lot of possibilities there. You could use skies for your backgrounds. Find textures. Do whatever. But those days are long over my friends. Or so we thought. Oh yes, there is a hack. Actually there are a lot of hacks out there, but as we know not all hacks are created equally. So without any further ado, I give you gogl.app. With gogle, you can get all that functionality back. Search for images over 10mp if you fancy. And also check on the rights that those images have. You don't want to end up getting into a legal battle with gettyone...trust me...you'll loose that one.
So, if you are looking to just do a quick image search and miss ye old functionality of google of the old days, then I would recommend gogl to have a few more options when it comes to your image searching pleasure.
