Hi
I just successfully uploaded 2 new jpg images without any problems - you can see the largest one on your sponsors page (delete it after viewing it). We also receive email notices if any of the sites using D-Web have a error when editing a page and so far we have received none from your site. So I'm not sure what you are doing wrong. Email us the 2 images you have been trying to upload and we'll see if we get an error also.
Make sure you are using the most current version of Internet Explorer - you can also download firefox (which is a better browser anyways) you can download that at
http://firefox.com - see if you still get the same error.
If you get an error copy it and post it here so we can see what's going on.
Also remember that your image file size can be no larger than 1,950 megs
