It’s possible for EasyCatalog to build a path to an image from the data, but this only works in there is a clear structure to the way the images are stored. For example, if all the images beginning with ‘A’ are stored in a folder called ‘A’ then you can build a path using custom field functions such as LEFTSTR(FIELD,1).
This can then the entered in the “Location” text edit area. Any of the custom field functions can be used, so as long as there is a discernible structure to the images storage.
If there’s no structure you can use the ‘Search For Image’ option to search a folder structure. This needs to be done after pagination.
