You need the GetChunk and AppendChunk functions.

Here are some MSDN pages about how to load and save images from Access databases:

• How To Read and Write BLOBs Using GetChunk and AppendChunk
• Reading, Storing, & Writing Binary Large Objects (BLOBs)

And here are two example databases for Access 97 and 2000.
(You want the module basBLOB from in there - the code is based on the second MSDN page)

OLE objects is bad way of storing images in MS Access. Use OLEToDisk (http://www.lebans.com/oletodisk.htm) to save your images as pic files.

After that reimport them in nice way. Check AccessImagine (http://access.bukrek.net) for working with images in Access - it does all the hard job.
