I use this for the photo album on my web site (http://www.guydavis.ca). It's not a high traffic site by any means, so performance isn't an issue. Can't show you PHP, but here's what I did in an Java servlet. It handles uploaded (POST) images from friends. byte_out is a ByteArrayOutputStream. imageIcon is an Icon that I create using JDK 1.4's headless AWT support to allow me to calculate the image's thumbnail dimensions. Connection con = WebUtils.getConnection(); String st = "INSERT INTO photos (location, description, date_shot, filename, mimetype, img_data, "; st += "height, width, thumb_height, thumb_width, category, access, title) "; st += "VALUES(?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)"; PreparedStatement stmnt = con.prepareStatement(st); stmnt.setString(1, ((String) params.get("location"))); stmnt.setString(2, ((String) params.get("description"))); stmnt.setString(3, date); stmnt.setString(4, (image.getFileName())); stmnt.setString(5, image.getContentType()); stmnt.setBytes(6, byte_out.toByteArray()); stmnt.setInt(7, imageIcon.getIconHeight()); stmnt.setInt(8, imageIcon.getIconWidth()); stmnt.setInt(9, thumb_height); stmnt.setInt(10, thumb_width); stmnt.setInt(11, Integer.parseInt((String) params.get("category"))); stmnt.setString(12, (String) params.get("access")); stmnt.setString(13, ((String) params.get("title"))); stmnt.executeUpdate(); Given that most of the photos posted by myself and friends are personal, I needed an access control system and I wanted something more robust than a publicly accessible image with a random name. The only way to do that is to have a servlet or CGI read in a image from disk or database (where's it's not web accessible) and write the data out to the client. Here's the relevant code from my PhotoServlet: String query = "SELECT * FROM photos WHERE id="+id; ResultSet rs = WebUtils.doSQL(query); if (!rs.first()) { displayError(request, response); return; } // if it's marked personal, only logged in people should see it if ((rs.getString("access").equalsIgnoreCase("Personal")) && (session.getValue("login") == null)) { displayError(request, response); return; } if (rs.getString("filename").toUpperCase().indexOf(".GIF") >= 0) response.setContentType("image/gif"); else response.setContentType("image/jpeg"); Blob img_blob = rs.getBlob("img_data"); InputStream in = img_blob.getBinaryStream(); while (in.available() > 0) buf_out.write(in.read()); buf_out.flush(); buf_out.close(); Here's the CREATE TABLE for my photos table: photos | CREATE TABLE `photos` ( `id` smallint(5) unsigned NOT NULL auto_increment, `location` varchar(255) NOT NULL default '', `description` mediumtext NOT NULL, `date_shot` date NOT NULL default '0000-00-00', `filename` varchar(255) NOT NULL default '', `mimetype` varchar(50) NOT NULL default '', `height` smallint(5) unsigned default NULL, `width` smallint(5) unsigned default NULL, `thumb_height` smallint(5) unsigned default NULL, `thumb_width` smallint(5) unsigned default NULL, `img_data` longblob, `category` smallint(5) unsigned default NULL, `access` enum('Public','Personal') default 'Personal', `title` varchar(255) default NULL, PRIMARY KEY (`id`) ) TYPE=MyISAM I don't see why you shouldn't be able to do something similar in PHP.
