Hi Mhankins!
Sorry I am so long with answere.
There is plugin styles in the file “polaroid_gallery.css”.
Find next line of style :
.polaroid-gallery a.polaroid-gallery-item .polaroid-gallery-text {
...
}
There you can change font-family and font-size.
For example I use next style on my own blog:
.polaroid-gallery a.polaroid-gallery-item .polaroid-gallery-text {
position: relative !important;
display: block !important;
line-height: 26px !important;
height: 26px !important;
padding: 0 5px !important;
margin: 0 -5px !important;
max-width: auto !important;
min-width: auto !important;
overflow: hidden !important;
visibility: hidden !important;
font-size: 22px !important;
font-family: "Poiret One", Georgia, serif;
}
Font family “Poiret One” is imported from google fonts.
If you need more detailed instruction I will be glad to help you.
