You should be able to add multiple albums to your profile:

Look for the link to pictures and albums. Each album is limited to 100 pictures but you can set up multiple albums.
Within these albums size limits for each pic are 1200 x 1200 pixels and a max file size of 1.9 MB per image.
The reason for the 100 pic per album limits is to keep page loads fast.
