You need to modify the Flash template. This is at

  • Windows: C:\Program Files\Adobe\Adobe Photoshop Lightroom 4.x\Shared\webengines\default_flash.lrwebengine
  • Mac: Applications\Adobe\Adobe Photoshop Lightroom [version]\Shared\webengines\default_flash.lrwebengine

Copy that lrwebengine to

  • Windows: C:\Users[user]\AppData\Roaming\Adobe\LightroomWeb Galleries
  • Mac: [user]\Library\Application Support\Adobe\LightroomWeb Galleries

Open the file galleryInfo.lrweb in a text editor. Notepad is fine on Windows, or TextEdit on Mac where you may need to right click the lrwebengine and select “Show Package Contents” to get to the file itself.

Look at line 21 and replace the following lines with this:

title = LOC “$$$/WPG/Templates/Flash/Bluefire1=Lightroom Flash Gallery > 500”,

id = “com.adobe.wpg.flash.bluefire1modified”,

galleryType = “Flash”,

groupPath = “resources/mediaGroupData/group.xml”,

mainSWF = “resources/gallery.swf”,

maximumGallerySize = 50000,
