Everything works fine, everything goes in the directory and mysql database, Gif photos display perfect, but the JPEG photos do not display clearly, Please I'm new your help to know the script code instruction will be really appreciated,

Thanks soooo Much Again, puddin!

Try changing this block of code in page 2:

if($source_handle)
{
// Let's create an blank image for the thumbnail
$destination_handle = ImageCreate ( $thumbnail_width, $thumbnail_height );

// Now we resize it
ImageCopyResized( $destination_handle, $source_handle, 0, 0, 0, 0, $thumbnail_width, 


$thumbnail_height, $size[0], $size[1] );
}

to:

if($source_handle)
{
// Let's create an blank image for the thumbnail
$destination_handle = ImageCreateTrueColor ( $thumbnail_width, $thumbnail_height );

// Now we resize it
ImageCopyResampled( $destination_handle, $source_handle, 0, 0, 0, 0, $thumbnail_width, 


$thumbnail_height, $size[0], $size[1] );
}

The difference is that first you are creating a True Color image, which will maintain the exact colours from the original image. Second, you are Resampling the image (as opposed to just resizing it). This compresses the image and maintains the pixel resolution of the image, thus no loss of quality.

Thank-you...


Your help has been appreciated, but now the Gif photos won't come up... I have tried replacing ImageCreateTrueColor with so many other image commands but i cannot get it. How does it accept both and bmp.... Thanks again, puddin
