Step 2

Layout -> Main page -> Thumbnails

Then set thumbnails width and height:

Then you have to set thumbnail insertion code, the only difference with Line output code is that {src} or {srcshort} variable is required.
If you do not use Brownie pages on other domains, you can use {srcshort} variable.

Thumbnail line for empty spots: If you do not have enough thumbnails to fill up the whole of your thumbpreview table, empty spots will be filled in with this code.

File type for additional thumbnails: If you use variables {contfiletype}, {imgfiletype} or {movfiletype}, code for this file type (from Line output -> File types) will be shown for permanent links and Thumb 911 links.

Gallery type for additional thumbnails:If you use variable {type}, code for this gallery type (from Line output -> Type) will be shown for permanent links and Thumb 911 links.
