How can I get xplorer2 to show thumbnails for jp2 files? The all show up with a generic icon, in my case a red blob which is the standard icon for my photo handler program Irfanview.

x2 Pro 2.5.0.4
Win 7 Pro 64 bit

have you tried sagethumbs plugin?

Sagethumbs only "displays thumbnails" in the sense of displaying one thumbnail for one selected file at a time in a preview pane or right-click context menu. It doesn't make Xplorer2 or Windows Explorer display thumbnails for all the files in a folder at the same time, at least not for jp2 files. It sort of sounds like it does based on things people say online and the program's website ("Extended thumbnail image view of Explorer folder" - this could mean anything and there's no further explanation). But I installed it and can't find any way to get jp2 thumbnails.

try a google search for JP2 thumbnails windows explorer. Here is one result that talks about sagethumbs and another shell extension
