Show all pictures - goine

[sabio]

Hi,

 

Recently the link "Show all pictures" on some products have disappeared.

 

The products affected are those with attributes. Example; A pair of shoes are displayed in different colors and sizes. In total, at first sight, 5 pictures are displayed. When choosing let's size black size 41 all other pictures disappear (as they shall) and only the picture with a black shoe is visble.

 

Now, before, there was a link saying - display all pictures, but now it's gone. Suggestions what I've might have done wrong :-)?

 

Regards.
