I'm willing to bet that your Photoshop document is a higher resolution than the image you are downloading from the web. So even if it has high resolution, it might look blurry because the canvas size is very large.You can drag up the size on your own, but it will result in diminishing the quality of the image (pixilization, blurriness). In Photoshop go to Image > Image size and check the dpi of both images there.

Hope this helps.

The ppi setting has no relevance whatsoever here. That only matters when you send to print. This is about pixel dimensions.

The answer is in this thread, exactly the same issue (I'm not typing it all again): https://forums.adobe.com/thread/2316938

...or rather, to be precise: By dragging, the file is opened into another file as a Smart Object. This causes the ppi setting to interfere as an unwanted (in this case) side effect.

The point I'm trying to make is this: Don't open as Smart Object until you know what a Smart Object is and what it does.

So there I had to type it again after all...
