Attach big image

Hello!

I am new to DS, but was using AUTOCAD maps earlier.

Using last x32 win version(download it 3/03/2014).

So i trying to attach image to use it as layer(google maps)

But when i try to add image(80mb) it tells me format not supported.

I trying to add .png and .jpeg.

big images dont work, but small one adds fine.

can i fix it somehow?
