Do you mean here:
/ public_html / image / data / media
...yes, kind of
...more like (in FTP) /public_html/yourgallery/data/media
You will have folders with numbers in the media folder. Those numbers correspond with your categories.
So when looking at your gallery home page place your cursor over a category and look at the link, it will show something like:
www.yourdomain.com/yourgallery/categories.php?cat_id=1Each category has a number assigned to it.
So if you go to a category (in FTP) it would actually look like:
/public_html/yourgallery/data/media/1
Where
1 would be the category ID
Did I just over explain this? Oh well, you get the idea
