Google used to have a really nice and easy way to search for images, but with certain resolutions, either higher or lower than. For some reason they removed it, I suspect it came after the changes to Google Images relating to copyright cases that were brought on them (just a random guess).

You can however still refine your search results using Googles Advanced Search, or you can use some added search parameters. As this is a short post, for now, until this is updated I’m just going to provide a link.
