Themes doesn't applied ?

[focafo]

Hye,
I try to install a "theme" from your site.
I follow this instruction but nothing happens :
"Go to Joomla! Administration » Components » Phoca Gallery » Themes » Select the Theme file from your harddisc and click on Upload File & Install."

I'm on Joomla 3.2 and I use PhocaGallery V4.0.3 and I don't find the possibility to follow this instruction :
"You can change the design of your gallery very quickly and simply :
Go to Components » Phoca Gallery » Themes and select:
Apply to Component (only Color Variation in Default Settings of Phoca Gallery component will be changed)
Apply to Categories (all Color Variation in all Phoca Gallery Categories Menu links will be changed) - only in Phoca Gallery 2.x
Apply to Category (all Color Variation in all Phoca Gallery Category Menu links will be changed) - only in Phoca Gallery 2.x
"
After the upload, what I have to do ? go to style ? and change what ?
thanks in advance

ps : I've read https://www.phoca.cz/documents/2-phoca-g ... lery-theme
but I don't understand what to do, I'm not familiar with css and other

Hi, for now there is no theme for Phoca Gallery 4, as Joomla! 3 is still not stable LTS

Since Joomla! 2.5 there are no content settings in menu links, so both Apply to Categories and Apply to Category options were removed.
