Display photos and folders titles and other doubts

Hi to everybody!
I’m new to wordpress and so I have some issues with advanced configuration.
I was a piwigo user,that is a great engine for image galleries,but its really poor for seo standards,and so I’ve decided to try wordpress,that is realy great.
I have to create a news blog with an image gallery(really huge),and so I’m using eazyest gallery because is the only one that allow me to use an already existent folder instead of the default wp_content/gallery, and also mantains the subfolders structure.I’ve tried to use other galleries,but because I can add photos only in the default folder,considering also that I have a lot of subfolders,the lenght of the resulting links will become excessive and out of seo standards.
so I’m using eazyest gallery,but I don’t know how to display titles under folders and thumbnails?I think that I have to put css codes,but I’ve not undestood where!
Can you help me?thanks a lot
