Hi, You are looking for blob. I recommand you to store the image a base64 on a text blob rathet then a binary blob. The reason is simple.. backup and restore of data.

Hi all, I would like to be able to store images inside a postgresql table (inserted WITH a lazarus app) then retrieve them again and display them from inside a different lazarus app. XPM would do, but jpg would be ideal. I am guessing the process would be something like this: Inserting an image: Use a TImageSelect dialog to select the filename Load the file into a TStringList; SQL Insert TStringlist.Strings (Easiest way to get from file to string) What would be the best SQL type to store it as ? BLOB ? Retrieving: SQL Select Image Read the result into a string Store the string into a Tmemorystream TImage.LoadFromSTream(TMemoryStream) This brings up a few questions though: 1) How can I store a string into a TMemoryStream ? I know that TStringList has a loadFromStream method - but how d I go the other way around ? Is there a BETTER way I should using ? A.J. -- A.J.
