Thumbnail problem.

We have encountered problems with the java version of ImageUploader v. 2.0.50. We upload two different pictures onto our server the first fits in a 80x80 square and the second 1800x1800. We then insert them in the database.

Some of our clients upload fair sized pictures but what we get is a pictures that fit a 100x100 square. The small thumbnail (80x80) always seems to work fine. It is a very strange behavior considering that we do not mention 100x100 thumbnail in the config files, and when it happens to a user it has problem on most of his pictures but not all. We have noticed a few users that only have one bad picture.

Here is our aurigma config file :

iu.addParam("FileMask", "*.jpg;*.jpeg;*.jpe");
iu.addParam("MaxDescriptionTextLength", "400");
iu.addParam("MaxFileCount", "100");
iu.addParam("MaxTotalFileSize", "");
iu.addParam("MinImageHeight", "0");
iu.addParam("MinImageWidth", "0");
iu.addParam("Charset", "ISO-8859-1");
iu.addParam("UploadSourceFile", "False");
iu.addParam("FilesPerOnePackageCount", "1");
iu.addParam("UploadThumbnail1FitMode", "Fit");
iu.addParam("UploadThumbnail1Height", "80");
iu.addParam("UploadThumbnail1JpegQuality", "100");
iu.addParam("UploadThumbnail1ResizeQuality", "Medium");
iu.addParam("UploadThumbnail1Width", "80");
iu.addParam("UploadThumbnail2FitMode", "Fit");
iu.addParam("UploadThumbnail2Width", "1800");
iu.addParam("UploadThumbnail2Height", "1800");
iu.addParam("UploadThumbnail2JpegQuality", "90");
iu.addParam("UploadThumbnail2ResizeQuality", "Medium");
iu.addParam("ShowUploadListButtons", "true");
iu.addParam("ThumbnailHorizontalSpacing", "15");
iu.addParam("ThumbnailHorizontalSpacing", "15");

And here is the php code that we call :

function saveUploadedFiles()
{
	if (!$_FILES["Thumbnail2_1"]['size'])
	{
		return;	
		
	}
	$fileName = get_safe_fileName($galleryPath);
	move_uploaded_file($_FILES["Thumbnail2_1"]["tmp_name"],  $pathto . $fileName);
	
	if (!$_FILES["Thumbnail1_1"]['size'])
		return;	
	move_uploaded_file($_FILES["Thumbnail1_1"]["tmp_name"],   $pathto . $fileName);
}

Thank you.

we have the same problem with imageuploader.

In some cases just thumbnails (size about 100px)

or even icons are uploaded instead of the thumbnail

we have defined in the html-source.

We don't believe, that the reason for this situtaion

are the sourcefiles, because in series of fotos taken

with the same digicam these small thumbnails appears

sporadic. But sometimes this appears in a sequence,

so that every 2nd or 3rd image is just such a little

thumbnail.

All images should have a max. width and height from 2000px.

This ist what we use in the html-source:

iu.addParam("UploadSourceFile", "false");
iu.addParam("UploadThumbnail1FitMode", "2");
iu.addParam("UploadThumbnail1Width", "2000");
iu.addParam("UploadThumbnail1Height", "2000");
iu.addParam("UploadThumbnail1JpegQuality", "75");

To avoid this small thumbnails we thought about to

check the filesize. If the size of a file is less then

e.g. 5kb, the php-script send a header("HTTP/1.0 400 Bad Request");,

so that imageuploader uploads the file again.

But in the worst case the image is uploaded an uploaded

like in an infinite loop.

What do you think about this solution?

Maybe you have some other ideas to avoid.

Thank you and kind regards

P.S.: We use iu version 4.0.27 (activex) and 2.0.50 (java)

and this appears in both versions.

We have tested your code snippets again and again and there were no problems with thumbnails. As I understand the problem occurs on some explicit files and not every time. We need these files to test. Also we would like to get the Java console dump of the error and upload script. We need everything which could help to solve this problem (Java or ActiveX Uploader is used, which system, browser, JRE and so on).

Your wrong file check is good enough. Any way we need the files which were the reason of the problem just once because we could make a lot of copies and upload them a lot of times. That is the only way to reproduce the bug. What E-mail address have you sent us the photos from (you may answer by PM ;) )?
