I'm not sure what you mean Stoleti. GD Library is using GIF and PNG formats since v2.0.32. The manufacturer is now up to v2.0.33.

Well the watermark its just working with jpg images .....


GIF,PNG.....doesn't work... 

[TheOracle]

Which version of GD do you have ?

[V@no]

in includes/image_utils.php find:

Code: [Select]

    $image_handle = "image".$types[$image_info[2]];replace with:

Code: [Select]

    $image_handle = "imagejpeg";

[TheOracle]

Is it also possible to add these types in an array in case of additional extensions that would be involved ?

[V@no]

what?

[TheOracle]

Yes, of course - an example :

$image_handle = "imagejpeg";

Would there be a way to do it like this :

$image_array = array("imagejpeg", "imagegif", "imagepng");

if (in_array("imagejpeg")) {
$image_handle = "imagejpeg";
} elseif (in_array("imagegif")) {
$image_handle = "imagegif";
} elseif (in_array("imagepng")) {
$image_handle = "imagepng";
} ###### End of if statement.

?

This would be useful since GD also involves GIF and PNG now.

Recall: The above is just an example. The rest of the $image_handle's equalitys might not even exist as a name.

in includes/image_utils.php find:

Code: [Select]

    $image_handle = "image".$types[$image_info[2]];replace with:

Code: [Select]

    $image_handle = "imagejpeg";

This doesn't work ... images still with same format (original) and not change to jpg/jpeg...when upload


My GD 2.0.28

@V@no:

Sorry, I meant something like this (more appropriate) :

if (preg_match("#(jpg|jpeg)$#is", $image_handle))) {
$image_handle = "imagejpeg";
} elseif (preg_match("#(gif)$#is", $image_handle))) {
$image_handle = "imagegif";
} elseif (preg_match("#(png)$#is", $image_handle))) {
$image_handle = "imagepng";
} ###### End of if statement.

Could something relative be done ?

Replacing $image_handle = "image".$types[$image_info[2]]; with that ?

@Stoleti:
possibilities:
1) you did not change the file on the server
2) you made a misstake
3) you are not using GD as graphic module in 4images

@TheOracle:
1) the extension can be deceptive
2) your example is equal to this:

Code: [Select]

    $types = array(1 => "gif", 2 => "jpeg", 3 => "png");
    $image_handle = "image".$types[$image_info[2]];which is already present in 4images, except its slower.

[TheOracle]

Does this bolded part :

$types[$image_info[2]]

means JPG in this case ? (2nd number in the array)

[V@no]

means JPG in this case ? (2nd number in the array)

No, it conteins type of the image. More info here
