Automatically mark images on result list that matched a user defined rule.
There are 2 types of rule, comparison rule (the ones with icon) and property matching rule.
The comparison rule will compare a property among images on each group and mark the matched ones. E.g.: mark all images whose size are smaller on each group.
While property matching rules will mark all images whose property are matching a given value. E.g.: mark images whose file name contain “copy” text.
