Facing problem while uploading the image!

I am facing problem in uploading the image in my news for the version 2.5, my site is www (dot) latestmp3 (dot) co (dot) in. Even the same type of problem I am facing in the site seonews (dot) aninfosolutions (dot) com. Please guide me how can I upload the image properly in these sites, with my news. I don’t want to upgrade the WordPress version cause I fear I might lose something during the procedure.
