I'm having a seeming common problem with album.  I'm getting "No pictures selected for upload or unknow error"... but not for all pictures.

I can upload jpg, gif, png, all that happy stuff.. but it seems like as soon as I get to a large file size, upload stops working.  I've narrowed it down to right around a 2MB limit. I can upload a 1.8MB image.. but not a 2.1MB image or larger (all JPG so far)

I've configured the album upload settings as such:


These settings seem more than sufficient to allow the uploads.

Is there another setting that I should be modifying?
