A novice like myself has one question :
I have a few images users uploaded to a mySQL database. How can I out
them as thumbnails.
Any help would be appreciated.
<?php
$file="demo.jpg";
$img_name="images/$file";
$new_name="thumbs/$file";
$max_width=120;
$max_height=70;
$size=GetImageSize($img_name);
$width_ratio=($size[0] / $max_width);
$height_ratio=($size[1] / $max_height);
if($width_ratio >=$height_ratio)
{
$ratio = $width_ratio;
}
else
{
$ratio = $height_ratio;
}
$new_width=($size[0] / $ratio);
$new_height=($size[1] / $ratio);
$src_img=ImageCreateFromJPEG($img_name);
$thumb=ImageCreateTrueColor($new_width,$new_height);
ImageCopyResampled($thumb,$src_img,0,0,0,0,($new_width-1),($new_height-
1),$size[0],$size[1]);
ImageJPEG($thumb,$new_name);
ImageDestroy($src_img);
ImageDestroy($thumb);
print "<img src=$new_name>";
?>
The above is some old code i had on the hard disk .
If memory serves $img_name="images/$file"; is where it gets the large
image from and $new_name="thumbs/$file"; is where it puts the thumbnail
you just created .
$max_width=120;
$max_height=70;
You can change these maximum thumbnail size defaults to suit afterwards
if wanted .
