Is there a way to ensure that the Download option takes the Image from "_source" folder rather than the "Gallery" folder? After all we get the thumbnail which we can right click and save and then the Slideshow / Popup which we can also right click and save - The download should com from the _Source or am I doing something wrong?

The module is designed to let you download the images that are only as big as the size that was configured in the settings for that module instance. I do see it could use the functionality you suggest, but it is not possible in its current state.

Do you know the truth when you hear it?

So is there a setting that can be set to ensure that the download IS the from the _source directory? This is really important and your reply suggests a "nice to have" but not a solution -  I am a developer sois there somewhere in the source that can be tweaked to enure that the _source is the image to be downloaded?

 The logic to consider is:

  • Gallery has a storage limit
  • The DNN install has a file size upload limit
  • Each Gallery module instance has an image size limit.
    • When the _source file is bigger than the Gallery image size limit, it will be resized.

If you can control the size of _source files, then you can make the Gallery Size limit the same as the _source limit. And you will not need to change the code. Otherwise you will have to dig into the Gallery source code and change the logic to look into the _source folder for the right file. As I said, the current version does not have the functionality you are looking for.

As Nestor indicated, download of the original, full-size image from the _source folder is not a option in the current version. I agree that it would be a good feature but due to bandwidth concerns for very large images should be one that can be enabled in the module configuration, not by default.

The code which generates the download link (using the core LinkClick file streamer) is found in the method GetDownloadURL beginning at line 649 in File.vb. Since only the FileID of the re-sized preview image is retained in the metadata, it would be necessary to modify the filepath to point to the _source folder then call the core method FileController.ConvertFilePathToFileId method to obtain the proper FileID to pass to the LinkClick method. Please note, however, that only image files have their original, full-size image retained in the _source folder. Flash and video files are uploaded only to the main folder of the gallery or child album and would have to use the existing code to generate their download urls.

As Gallery v 4.03.00 has now passed release testing, the source package is available for download and the most recent source code change set (same as package) is available on the project's Source tab - both at http://dnngallery.codeplex.com.
