How can I upload photos from my Android (4.1) to Picasa without resizing to 2048 resolution? I am paying for additional storage, so the storage limit doesn't concern me.  I would like to upload full-resolution pics from my phone to my Picasa albums, but when I choose to upload a picture from my Android to a Picasa album, the picture ends up being resized to 2048 pixel max resolution.  Is there any way to disable this or bypass it without using something like Dropbox instead?

Using Nexus S running Jelly Bean.
That is described at the Google Support page for Picasa as a limitation, even if you're currently paying for extra space, that doesn't allow you to have image files larger than 2048 pixels on their longest edge:


Picasa and Picasa Web Albums - Free storage limits 


  Free storage limits
  
  Photos up to 2048 x 2048 pixels and videos up to 15 minutes won't count towards your free storage.
  
  Automatic resizing
  
  All photos uploaded in Google+ will be automatically resized to 2048 pixels (on their longest edge) and won't count towards your free storage quota.
  
  All photos uploaded from the Picasa software or in Picasa Web Albums over the free size limit will count towards your 1 GB of free storage. When you reach your storage limit, any new photos you upload larger than the free size limit will be automatically resized to 2048 pixels (on their longest edge).

You can refer to the How Google storage plans work, to confirm that what you pay only affects the space you have, not the service characteristics.
