the jpg pictures go into a temporary 'cache'....and unless you 'save' them...that is, tell the computer to put them into a permanent spot, they will eventually be overwritten--just like cleaning out your closet now & then to make room for new clothes. If you try to save ALL your clothes or pictures, you will eventually run out of room...but it is true that 4 or 5 of those pictures are not likely to have been your problem, unless you had been online a long time, doing lots of stuff in Windows and THEN tried to do some big graphics!....Windows simply doesn't handle memory issues real well and even the best of us will have freezes and other problems and need to re-boot in order to clean up...*sigh*...
