Hello Vintageornew -
We are not aware of any issues with the image uploader and when I tested this in my own account, I did not run into any difficulty uploading images and the uploader functionality appeared to be normal for me. As such, I suggest that you first try clearing the cache of your browser to ensure that none of the site pages have been erroneously cached. If you are uncertain how to clear your browser cache just enter the name of your browser and "clear cache" into your favorite search engine to get the steps to do so.
If the difficulty persists after you have cleared your browser cache, please file a support case from under the Help tab of the site letting us know the name of your browser and the operating system of your computer as well as a description of what you are encountering and our support team will take a look into it for you.
