Images will not show up

[olaf]

Hallo,

I have a problem with one of my applications, the strange thing is that it happens only by 1 % of the users.

I can't post an URL because the area is password protected.

It's about a page with an overview of products (thumbs) like a catalog. All the images are resized with this function:

function thumbs($file_name_src, $file_name_dest, $weight, $quality=100) {
	$size = getimagesize($file_name_src);
	$w = number_format($weight, 0, ',', '');
	$h = number_format(($size[1]/$size[0])*$weight,0,',','');
	$dest = imagecreatetruecolor($w, $h);
	imageantialias($dest, TRUE);
	$src = imagecreatefromjpeg($file_name_src);
	imagecopyresampled($dest, $src, 0, 0, 0, 0, $w, $h, $size[0], $size[1]);
	imagejpeg($dest,$file_name_dest, $quality);
	imagedestroy($dest);
}

I'm not sure that there is a problem. The two systems where this is happend are windows PC's with IE6.

do you mean the users get the box with the red x (broken link) or the place where the image shows up is just blank?

i have had similar problems in the past. a lot of times it turns out to be something in the filename that was uploaded that messed me up. i.e. it was either a space character somehow creeped in causing the problem, or special characters, etc.

you may want to review your code where you validate your uploaded file names.

personally, i have made it a policy to rename any file that is uploaded to a standard of my own liking and that has greatly reduced the number of broken links experienced

i'm not sure about how different browsers handle file names and <img> tags, i don't know why it would occur on one browser and not another.

anyway, these are just suggestions from my corner of the world, since we can't see the problem duplicated, it is kind of hard to pinpoint exactly what the problem is.

Yes there are the red crosses...

There can't be a problem with the names because they are uploaded by myself with ftp.

After upload, I resized the images with my function. Strange is that one image is shown like it have to be.
