I am simply tring to use imagecreatefromgif() to create a gif. I keep getting the following error:
Warning: imagecreatefromgif(): '/home/omnipcs/public_html/devel/example/components/com_mtree/img/listings/34_test.gif' is not a valid GIF file in /home/omnipcs/public_html/devel/example/components/com_example/includes/example.image.functions.php on line 36
The file is indeed where it should be, it exists, and is a gif that I JUST created in photoshop. I cannot seem to get around this error and I have found nothing on the web to help me.
Can anyone here shed any light onto why I am getting this error? This is how the function is being called:
$logo = imagecreatefromgif($image);
Image points to: /home/omnipcs/public_html/devel/example/components/com_mtree/img/listings/34_test.gif
Which like I said, exists and is in fact a gif.
I have even gone so far as to try this all using jpg's. I don't get any errors but my resultant image is blank. What gives?

also, can you post your code that youre using to display image files?
I say old chap, that is rather amusing!

looking at the gd home page and then following it to [a href=\"http://www.nyphp.org/content/presentations/GDintro/\" target=\"_blank\"]http://www.nyphp.org/content/presentations/GDintro/[/a]
i came across using getImageSize to print out the images pertinent info. I am getting this:
Array (  => 220  => 136  => 2  => width="220" height="136" [bits] => 8 [channels] => 3 [mime] => image/jpeg )
for a gif. Note the mime setting. Why on earth would this happen? Could it be an improper server config?
I just made a rather awesome graphic in paint and tried using it. Same thing, mime-type came back as a jpeg.

obviously the mime-type of my gif is being altered upon upload and storage on the server. when I manually upload and run this code, all is well. when I upload from my browser, it breaks.
Anyone have any insight?
