Topic: Images not displaying on website - Help.

Everything working OK on local machine but most of my images and thumbs are not displaying on the website after I have uploaded it. It's not a simpleviewer issue but what else could it be? Could it be the images themselves and their values or maybe something the hosting company has set such as security software (they are not very helpful) :? The images are on the server but I cannot even see them even when I point to them directly.... Running latest IE incl. all patches.
Anyone, pleeeeease? I am pulling my hair out.   roll
