|Try this to upload panaorama pictures...
First, make a copy of your large image and resize it so that it has a ratio width/height of 2,5 or more (keep in mind that 800 pixels is the overall max limit, and 250 pixels the minimum. That is why I use a top/bottom frame from time to time).
Then upload it as usual. When that is done, you go to your profiles and choose Manage. You see the last picture you uploaded on top. Next to it, on the right, you see a link 'large post'. Click that, and upload the panoramic picture. There are some limits too, like 400 Kb is the max size for the large picture, 5 Mb for all your of large posts, and max. 3000 pixels width (I'm not sure about this last dimension, but you can check the limits in the 'upload large post' window.
