Thumbnails and viewing pics

[Ontario55]

I just burned pics to a CD

The thumbnails are blue and yellow

No indication what the pic is about

How do I get the thumbnails to show pic detail

 

Next question is when I open one, I can't advance to the next pic and the slideshow doesn't advance

I have to close the pic before I can open the next

Too time consuming

Appreciate some help

Thanks

This doesn't sound related to ImgBurn, it just burns what you give it to a disc.
