Sorry, not the clearest of titles!

This is my first post on DevNetwork, looks like a great community you've got here!

Anyway, onto my problem:

I have been outputting jpg files through a php script using the following code:

Code: Select all

$file['file_size'] = filesize($local_file_name);
	$file['file_name'] = basename($local_file_name);
	$details = getimagesize($local_file_name);	
	$file['file_type'] = image_type_to_mime_type($details[2]);

	header("MIME-Version: 1.0");
	header( "Content-length: {$file['file_size']}" );
	header( "Content-type: {$file['file_type']}" );
	header( "Content-transfer-encoding: 8bit");
	header( "Content-disposition: inline; filename=\"{$file['file_name']}\"" );

	// read and output the file in chunks to bypass limiting settings in php.ini
	$local_handle = @fopen($local_file_name, 'rb');	
	while ( !feof($local_handle) ) {
		print fread($local_handle, 8192);
	}
	fclose($local_handle);

	//Note: the same problem occurs when using: "print file_get_contents($local_file_name);" instead.
In the browser this displays images perfectly – no problems what-so-ever. However I have been loading this image into Macromedia Flash… Flash displays the image flawlessly, however the next time I try to change url, internet explorer just goes to a blank page! After that, back and forward buttons all go to blank pages too! The user is screwed until they press refresh, then everything is fine again. (Doesn’t happen in Safari, FireFox or Opera, and never happens when directly loading an image file!)

Can anyone see any glaring errors with my headers or shed any light on this. My assumption is that Flash is still trying to communicate with the server about the image for some reason and the next request just kills everything?

Any ideas would be greatly appreciated,

Thanks,

James

Sorry feyd, will make sure my posts are a little prettier!

Does anyone have any suggestions as to why I might have been killing ie?

Thanks, James
