Camera Image Filenames

Back in the old days with 2.0 and 2.1 on my Droid, any picture had the filename format of YEAR-MM-DD HH.MM.SS

For example: 2010-03-06 14.50.57

After updating to 2.2 now the filename is:
IMG_YYYYMMDD_HHMMSS

So the above would be IMG_20100306_145057

That's a bit tougher to read, when browsing through pictures. The spaces and periods do make a difference. Is there a way to change how the Camera application saves file names?
