New and Different Blogger problems

At first the switch to Google Blogger seemed to go smoothly...perhaps too smoothly. Currently I can't get into my account on the Mac, but I can just fine on the PC. However, once on the PC, I can't upload pictures from Blogger. I click on the little picture icon, choose my pictures - that's all fine, but there's no button to upload. The only way I've found to get pictures is to send them one at a time from Picasa. It works, but its not elegant (or fast). Sigh.
