Thank you! This test has now concluded and been updated. You can read more about the test in the Thumbnail Size Testing Tool article.
Please note: This change applies only to the Beta Testers who were not included in the first thumbnail size test. Also, this is a temporary change that will be happening later today, and the test will last for one week or less.
We'd like to thank the Beta Testers who helped us test the thumbnail size changing tool! These tests help shape deviantART and we sincerly appreciate your participation and feedback!
In addition to the feedback we gathered from your comments on the size testing tool, this week we're going to continue our research by implementing a test that randomly assigns Beta Testers a different size for viewing thumbnails.
During this time, the Beta Testers in this group will not have the ability to change the size at which thumbnails are viewed. The purpose of this test is so that we can monitor the browsing habits for each thumbnail size, to get a sense of how effective each size is; however, you are more than welcome to leave feedback here on the article.
If you would prefer not to take part in this test, feel free to turn beta testing off for the next week. Thumbnails will return to their standard size if you turn off beta testing during this test period.
Thanks for helping us in improving the deviantART experience!
