Problems with uploading mesh to Second Life

Hi there,

I am having a problems with importing into OS and SL. The problem is that when I import a mesh with multiple textures, the textures do not import with the model. Some of them import, but are not attached to the correct texture faces. The texture faces themselves are fine, and I can manually apply textures to them in world.
However, I wish to distribute my models as .dae files, and would like them import complete with baked textures for the convenience of the users.

Any ideas appreciated. I am using Blender 2.65.

Thanks in advance.
