Then, you can set a watermark option by sending all images from the gallery to a CGSmartImage tag inside of your Gallery template.
So, something like this as an example:
Code: Select all
{CGSmartImage src=$image->file|escape:'url'|replace:'%2F':'/' alt=$image->title filter_resizetofit='1024,768,#000000' silent=1 noresponsive=1 noembed=1 filter_watermark='Your Watermark Here'}
