Topic: DISAPPEARING IMAGES! please help!!!

i know this problem has been addressed before but none of the answers given have been able to help me out!

so PLEASE HELP! i have 4 different tiltviewer galleries on my website and only ONE of them is having issues with disappearing images.

-i know that all the file names and file extensions MATCH the the file names and file extensions in the XML document. i just now made sure that all the extensions were lower case and it didnt change my situation. i made sure to re-upload all the images to my server and still nothing.
-i know that i am not over my bandwidth or storage limits and my server does not have size or DPI limitations, its a professional plan with a popular linux shared hosting company.

PLEASE PLEASE HELP as soon as possible!!! thank you
