Hi all.
I'm having a problem regarding image handling. Sometimes an image can be showed in browser normally (in my computer) but when I
upload it into my site that image is not valid, so there is an issue in my getimagesizes() function.
Is there any function to recover such problem? I used "if(file_exists($image_path))" but it couldn't solve the problem.
Input would be appreciated
Best Regards

How are you uploading your image?

What is reporting your image is not valid?

- From what it sounds like you are doing, you are uploading a file through
some form, then manipulating it's size. Is this correct? What happens
when you stop manipulating it's size and try to view just the uploaded
file?

Yes it is, but the uploading was going well (size is ok). When I show the image on the web using getimagesizes(), 'sometimes' such
image size couldn't be resolved.
Is there any function to define that image is ok or not?

file?

Size of image (after or before uploading) would be same. but the issue still there (sometimes)

Size of image can't be define seem's like the image is not there, but it's not happened all the time.

Don't manipulate it's size and see if that works.

Can't help with sporadic problems -- that's probably a logic error.

What types of images are these? JPG, PNG, GIF?

Its jpg. Look I don't know exactly what your point, I'm just asking you about the function to resolve the size of image like the
codes below:
if (file_exists($img_path)){
list($width,$height) = getimagesizes($img_path);
}else{
$width = $ height = $max_size;
}
So is there any other option to replace file_exists();?

Well, if I do remember correctly, then you are uploading a file. If
that's the case, then rather than using file_exists() you should be
using is_uploaded_file. you've verified that is_uploaded_file()
returns true, then use move_uploaded_file() to move the file to
someplace on your filesystem. If that returns true, then you should not
have to check file_exists again and just be able to use get getimagesize().

So, a good function for this would probably be:

function getUploadedImageSize($image, $to_path) {
global $max_size;

$width = $height = $max_size;

if (is_uploaded_file($image)) {
if (move_uploaded_file($image, $to_path)) {
list($width,$height) = getimagesize($to_path);
}
}

return array($width, $height);
}

list($width, $height) = getUploadedImageSize($tmp, '/the/final/path');

BTW, I don't know if you did a copy and paste from your code or if you
just typed it in really quickly, but you do have a few syntactical
errors in the code above. First, the image sizing function is
getimagesize - singular, not plural. Second, in your assignment
statement, you have a space where there should not be one:

$width = $ height = $max_size;
^

Just wanted to make sure you knew about that in case it was copied and
pasted.
