Hello,
You can increase the height here and this should help give more room:
#s5_pos_custom_1 #myGallery {
height: 750px !important;
}
s5_responsive.css (line 103)
And you can also modify the position of the text too here:
.jdGallery .slideInfoZone {
top: 12% !important;
}
s5_responsive.css (line 225)
Regards,
