Google's own social network, Google+, has added functionality that allows users to zoom into pictures from within their web browser. This follows Google+'s early success with photographers; its addition of the zoom function will increase the popularity further with this group. Currently, however, the maximum upload resolution is capped at 2048 pixels, which limits the effectiveness of this addition. This upload cap can be bypassed through using Picasa or the Android uploader to post images.
Unfortunately, at higher resolution, Google+ fails to retain image quality through numerous compression artifacts, however this is likely to be resolved in time. The addition of the high-resolution image uploader is not uncommon, with sites like Flickr and Facebook embracing high-resolution image before Google+. In-browser zooming is also not uncommon, and has existed in Google's Picasa Web Albums and Microsoft's SeaDragon technology.
