Support Forum

I have a medium sized forum that has imported fine, but the biggest problem is that none of the attachments are showing up. Other images that were inserted into the posts seem to be showing up. From what I could find in the forum (nothing specifically about this) and other places on the web, it seems that it is not possible to import the attachments, is this true? is there any way at all to import and keep the attachment info? I initially had the vbulletin attachments stored in the data, no attachments imported, then I changed the vb install to store attachments in the file system. Again, no attachments were imported.  I am seeing that the same is true of bbpress into simple press. any resolution or work around for this??
