Another .htaccess question?

[GottaDiesel]

I have a dir that looks like this:

http://www.domain.com/webstore/web_store.cgi?keywords=pic11111lg&detail=yes

I would like it to come up when this:

http://www.domain.com/store/pic11111lg

is entered. The 'pic11111lg' part is the part that would variable... specifically the part between the 'pic' and the 'lg' could be a number from 1 to 10000000.

Does that make sense?

Thanks again,

Pete
