Thanks, yes I've done that overnight since your suggestion, and now have this 
problem:

My gambas code goes something like this and I've selected the png file to load 
which has been passed to this routine as ImagePath.

Public sub Save_Image(ImagePath as string)

 Dim img As Image
 Dim pictureData As String
 Dim sql As String
 
  img = Image.Load(ImagePath)  ' Save temp image as png file
  tempFile = Temp() & ".png"
  img.Save(tempFile)


  pictureData = File.Load(tempFile) 'reload as a string


At this point the pictureData string seems  to be ok.

I Then tried writing to the database:

  sql = "insert into temp_image(piccie)"
          "values($$"
    sql = sql & pictureData & "$$)"

and got back this message:

Query failed:ERROR: invalid byte sequence for encoding "UTF8":0x89 HINT: This 
error can also happen if the byte sequence does not match the encoding 
expected by the server, which is controlled  by "client_encoding"

Spent a couple of hours trawling the postgres help and looking up 
client-encoding, pg_types  etc etc, but with my limited brain power I got 
nowhere

Any idea's?


Regards

Richard
