I have isolated the problem domain in the following script. Required files are below it. Assuming you have a db created, the script duly INSERTs. Remove the comments from //$size... and I get this error,"No Database selected", and yet you can $db1->getdb(); to simultaneously echo the db chosen. I tried ImageSX hoping to find a way round, but alas....I'm here with a bug report.

<?
require ("config.ini");
require ("mysqldb.obj");

$img_path = "C:\Program Files\Apache Group\Apache\htdocs\img\images\marked\image6.png";
//$size    = GetImageSize($img_path);

$db1 = new mysqldb();
$db1->setsql("INSERT INTO images 
	(img_desc,img_fname,img_fsize,img_ftype,
	img_xval,img_yval,img_tn_grp,img_cat,
	img_angle,img_admit,img_up_date) 
	VALUES 
	(\"$img_desc\",\"$image_fname\",\"$uploaded_image_size\",
	\"$uploaded_image_type\",\"$img_xval\",\"$img_yval\",
	\"$img_tn_grp\",\"$img_cat\",\"$img_angle\",\"N\",\"$img_up_date\")
	"); 

if(!$db1->deladdmod()){echo $db1->err ;exit;}
