File names change after uploading?

I chose PBase back in 2003. One of the main reasons was when uploading photos, it kept the exact name as in 20110415-051_SpringW.jpg
I would change the title, but if I right clicked to download my own photo to possible upload elsewhere, or save it to my own drive for a web version of the larger file, I still had the name 20110415-051_SpringW.jpg matching my larger file 20110415-051_Spring.NEF and 20110415-051_Spring.tif
At one point it changed where the file name became some odd characters like 133966223.qGqamuXx_20110415-051_Spring.jpg
At least it still had the actual file name at upload at the end. I use my naming conventions to locate my own original files on my hard drive when someone sees a photo on PBase and asks to license it or purchase it as a print if it is not already on my own reflectionsbyruth.com
Now when right clicking, the file name is 133966223.qGqamuXx.jpg
Most of my newer uploaded the past couple years I would always place my upload name into the description ( 20110415-051_Spring.jpg ) But I didn't do that for every upload because I didn't know your whole system would change.
That still leaves me to figure out the month and day so I can go to my hard drive to locate the original.
The only good thing for me is I keep my photos into albums
by state
then by my own Bucks County, PA
Spring
each year 2004 to current
Summer
each year 2004 to current
Autumn
each year 2004 to current
Winter
each year 2004 to current
When did this change and why weren't we notified? If I knew, I would have gone to each file to be sure I list under it the file naming convention allowing me to locate it.
