Automatic Thumbnail and GIF

[Irin]

Hello,

 

I have installed an "Automatic Thumbnail" contribution. Almost all of my pictures are GIF and step 5 of the instructions say:

5. Go to the bottom of the catalog/includes/functions/html_output.php and insert before the ?>

  if your Webspace has GIF read and write ability delete GIF in the following text at $not_supported_formats = array ("GIF"); // Write in capital Letters!!

 

 

function thumbimage ($image, $x, $y, $aspectratio, $resize, $cachedir){

When I delete GIF in

$not_supported_formats = array (""); // Write in capital Letters!!

per instructions, I have all of my pictures shown on a black background instead of transparent. How can I change their background?

 

Thanks in advance,

Irina.

[Jodoi]

I have exactly the same problem as above...is it possible to fix this?

[1_musketeer]

I am having the same problem with transparent backgrounds being changed to black backgrounds by automatic thumbnail V1.7

 

It works perfectly if there is already a background in the image.

 

Has anyone found a solution to this?

 

Any help would be much appreciated as this is a great contribution which is really needed.
