Since PHP v5.1 the GD function imagepng() accepts compression argument. The compression argument must be from 0 to 9. 4images is using the compression settings when creating thumbnails or image resizing for jpeg images which can be from 0 to 100. Because of that using imagepng() function will return fatal error
PHP Fatal error: imagepng() [<a href='function.imagepng'>function.imagepng</a>]: gd-png: fatal libpng error: zlib error in example.php on line 10
The fix is simple:
In includes/image_utils.php find: $image_handle = "image".$types[$image_info[2]];
Insert below: if ($image_info[2] == 3) $quality = 9;

Oh, that comes from thumbnail, which apparently doesn't use same list of MIME type as images...
Try this, in includes/upload.php find: (wrong!)
$this->accepted_extensions['media'] = $config['allowed_mediatypes_array'];
Insert below:
$this->accepted_extensions['thumb'] = $config['allowed_mediatypes_array'];
-
Dont work, in Admin Panel comes:
Image file uploaded: bioshock2_details.png
Error while uploading the thumbnail image: bioshock2_thumbnail.png
bioshock2_details.png: The file has an invalid format (png, image / png)
Image file deleted
Data not written to the database
Please Help me!

My apology, my suggestion above was absolutely wrong...
In includes/upload.php find:
foreach ($mime_type_match as $key => $val) {
Insert below:
if (in_array($key, $this->accepted_extensions['thumb'])) {
if (is_array($val)) {
foreach ($val as $key2 => $val2) {
$this->accepted_mime_types['thumb'][] = $val2;
}
}
else {
$this->accepted_mime_types['thumb'][] = $val;
}
}

WORKS VERY FINE!
Please write this fix in your first Post!
Thank you V@no, you are my Hero :P
