Image Cropped in ASP page

I have a table with a field called "IMAGE" I can upload and display fine, however maybe 1 out of 10 or so images get cropped on the view. All my images are 90x90dpi. Why would some images be cropped while others are not. if I right click and save the image from the ASP page, the file is correct so it is just my view of them. An example can be seen at http://www.dalbase.com/webviewdrswv/2003_list.asp? Note... All images have not yet been uploaded.
Thank you in advance.
