One of the main reasons that I have chosen WordPress as a news management system on my website is that it can upload large amounts of images in bulk. I've never had a problem with it, and at one point I've uploaded 50 images through using the Ctrl/Ctrl+Shift click method.
However, I upgraded to WordPress 2.6 and found that I could only upload one image at a time. I also recently upgraded to Firefox 3, so I don't know if it's FF3 or WordPress that's stopping me from uploading more than one image at a time.
Also, what's this Flash Uploader people are talking about? I can only use the Browser Uploader?
