Alien Abduction, abnormal disappearances!

(insert ex-files music here) Where do my pictures go that disappear from my post? This strange phenomena keeps happening, my blog looks so nice one day and the next day They are GONE! No goodbyes. nothing! Does anyone know how to fix this? So I usually re-load my pictures. Do they show up as two pictures for my visitors? Does this have anything to do with my beloved Macintosh? HELP..... This is Blogger Hell!!!! Are my graphics and photos being probed as we speak?
