[fixed] save selected / images

[Hank]

hi there,

W3D 2.2.3
OS: Linux

I'm not sure if this is a bug or just needs an improvement
I got a file with multiple images where total size of them is 18 MB
I select one object + 2 random images and 'save selected...'
New file has all images from original source
Strange, isn't it?
If they are not assigned to any material anymore, thus why I still need them in new file?

BR, Hank
