Topic: JPEG file compression using JPEGmini and Juicebox-Pro Lightroom Plugin

I have recently purchased the JPEGmini Pro Lightroom plugin to (as that company claims on their site at http://www.jpegmini.com) Maximize the Quality and Minimize the File Size of jpeg images to be used on my website.

The JPEGmini Pro Lightroom plugin works as a Post-Process Action when exporting in the Lightroom Library module. From my initial testing it works really well.

I also make extensive use of the Juicebox-Pro Lightroom Plugin v1.5.1 to create photo galleries on my website at ssdavies.net. However, the Jukebox Output Settings tab only offers lightroom’s built in JPG compression options - I would like to use JPEGmini as an alternative.

Is there any way I can set up the Juicebox-Pro Lightroom plugin to use the JPEGmini Pro Lightroom plugin instead of the Lightroom (and Juicebox) default?


MY WORKAROUND
1. Use the Juicebox-Pro Lightroom plugin as normal but then
2. Export the same selected photos via the JPEGmini 1,800p option
3. Rename all Spaces within the generated filenames as _ (as used in Juicebox)
4. Replace uploaded jpg’s with JPEGmini generated ones in Filezilla
These steps are very fiddly and time-consuming.

Re: JPEG file compression using JPEGmini and Juicebox-Pro Lightroom Plugin

Unfortunately, this may not be possible.

After activating the JPEGmini plugin, are all images exported by Lightroom (whether from the Library module or the Web module, where the Juicebox Plugin for Lightroom is) processed by the JPEGmini plugin?
Have you tried exporting a Juicebox gallery with the JPEGmini plugin both enables and disabled to see if there is any difference in the resulting image size? (I do not have JPEGmini so cannot run such a test myself.)

If not, then it sounds like JPEGmini might need to provide an API to allow developers of other Lightroom extensions to utilise their plugin's functionality (and, from taking a look at their website, there does not seem to be one).
Even if it was possible to hook into the JPEGmini functionality, the Juicebox Plugin for Lightroom would need to be rewritten to incorporate such functionality (the user interface and underlying functionality of the Juicebox Plugin for Lightroom is not something that can be modified by users as the web engine is compiled and cannot be edited) and I think it is unlikely that the developers would be willing to rewrite the Juicebox Plugin for Lightroom to support a non-free third-party plugin.

If the images exported for a Juicebox gallery are not automatically processed by JPEGmini when the JPEGmini plugin is active (i.e. if Lightroom's exporting functionality is not automatically intercepted and overridden by JPEGmini in all scenarios), then it sounds like your current workaround is, indeed, the best course of action.

I realise that this is not a solution to your problem but I hope that it at least helps to clarify things.
