Half of my player pictures show up on league site, other half doesn't (red x). Help!!

[Kammich]

Hey everyone,
I am having a problem getting all player images to work on my league site.

I have already renamed all of the player images to lower-case with a program, and all of the Team Logos to upper case so when I upload the photos they would match perfectly. It worked for the most part, but I am noticing what seems to be a common trend...

A lot of players are showing up in PNG format, as well as being listed by player ID.

For example...

A photo that works looks like this:
com/TestFile/images/orlando_cabrera.jpg

Those images are showing up perfectly fine. However... this is what's happening when the picture doesn't show up and I upload it onto the site:
com/TestFile/images/player_42582.png

It seems to be only minor leaguers, but I can't obviously confirm that because it would take forever to look at every file.

Furthmore, it would take even longer if I had to rename each and every ID.png on the site to get photos to show up. Is there any way I can strictly use the player's name on the file when adding photos? In other words... I'd like player_42582.png (who is Matt Wieters, just for example here) to show up like this:
matt_wieters.jpg

I just want every player to use the .jpg format upon uploading, because that is how I have my facepack set up...

Thanks a ton if in advance.

I'm going to move this to the Commissioners Corner forum as there may be someone in there who has had this issue before and may know the way round it.
