My assumption is that you are trying to store image data in a table and then serve it to the browser via FoxWeb.  I think that you need to use a Memo field in this case.  General fields are for storing OLE objects.  Memo fields can hold both text and binary data, so they work great for images.
 
You can use the code in the download.fwx example as a starting point.  All you need to change is where the data comes from.  Instead of reading it from a file via ReadFile, you need to read it from your table.
