Css specific for just one page

I need to use a css specific just for one page (ok, I could put my rules in main css, but since this stuff is for a contrib I'm developing and what I need is used only in that page, it would be optimized to put these rules apart).

I was working on a 1.3.0.2 version and I put my new css in /my_template/css/product_info_mycss.css

Everything ok, good!

Then I tried on a 1.3.5 and a 1.3.6

bad news...

my css is no more loaded.

Why?

I also tried to put my css under template_default/css/ but still nothing.

Why that worked in 1.3.0.2 and not in 1.3.5 and 1.3.6?

Thanks!

Just name it product_info.css and you should be good to go.

Very good, thanks!

Now it's working.

Now, before publishing, I only need to fix my contrib for who uses image handler.
