With the upgrade July 2013, I’ve changed the uploader to be more friendly.
On your photo album, you can upload multiple photos at one time. Click upload, and in the pop-up window, find the photos you want to upload. You can hold the key while clicking photos to select multiple. Click open, and a place holder will show up for each photo you selected. Once the photos are finished uploading the spinning circle will disappear and the photo will show up. Please be patient, it takes a little while after the progress bars hit 100% as the server is resizing all the photos and storing them away.
On the forum, when you reply to a topic, there’s a upload photo button on the right. When you click on it, you can also select multiple photos. Then when you click open, a place holder with a progress bar shows up for each photo you’ve selected. Once everything is uploaded, the spinning circle will disappear and photos appear on the right side.
