My b2evolution Version: Not Entered

Hope one of you experienced guys can help me figure this out.

My site is less than two weeks old. Two days ago I did a cpanel backup which topped out at about 24 Megs in total size. The most recent back up before that (four days prior) had a total size of about 8 Megs (Several blogs and pics were added during that time). Since this latest backup at most only four or five blogs and about 15 pics ( average size 120 Kb) were added to the site and none with pics posted. The strange thing is that now my cpanel is showing 75 Megs of usage, about 36 in public_html, and 39 in the Home directory. This great increase seems excessive. I cannot figure out why the sudden increase.

Is this a cache thing or temp files? I can't see it. Could this be related to the stats programs in my account?

On the public_html side, I am using the j-query image fit plugin and that seems to be producing several files in the evochache also.

Hope this makes sense. Any ideas or pointers would be greatly appreciated.

BTW, so far, I really like b2.

Thanks and regards.
