I don't know if that'd be a bug since those will change depending on the style used. That's why I made the border a stylevar, so you can change it per style without having to modify 20 templates
If you want to change the border color, it's in
ACP->Styles and Templates->Style Manager
Click Go next to the style you want to edit
Scroll down to DragonbyteTechMods and edit the color for dbtech_gallery_border
For the field length
ACP->Styles and Templates->Style Manager
Select Edit Templates on the style you want to modify
Expand Dragonbyte Tech: Gallery Templates
Open dbtech_gallery_view_image if you use New Style
Open dbtech_gallery_view_image_vb if you use vB Style
Whereever it says
Change it to like
