How to repeat a Variable Pair within a plugin start end tag

I wrote a plugin, called exhibit” that has a variable pair called “images”. Within the exhibit plugin start and end tag I would like to uses the variable pair “images in two different places …..

{exp:exhibit}

   {images}

    ... do some stuff ....

   {/images}

    ... do more some stuff ....

   {images}
   
    ... do some different stuff ....

   {/images}
        
{/exp:exhibit }

Right now the second images variable pair does not display anything. If I comment out the first images variable pair the second one work ok. This seems like it should not be difficult for the template processing to handle.

Any suggestions on how to handle this or links to code examples in the forum that could help?
