Micro Photo Album

[Zephlon]

Can someone modify this to support all images (including icons, if possible)?

PHP Code:

Why not just use an existing gallery script?

[Zephlon]

This is an existing gallery script!

...

I meant to post this in the support forum.

[Matt]

Yes, but I meant one that handles what you want

You did, but then it was magically moved here.

[Matt]

It's not a support issue

This script is everything I want except it only displays jpgs and jpegs.

Can you please either tell me how to do it or do it for me?

[Matt]

All of the code using JPEG-specific stuff would have to be rewritten to
1) detect what file type is in use
2) handle file types other than JPEG

That's a lot of code, and I don't have the time to handle it.

[Zephlon]

I think I got all of it except, how would I modify this code to support .jpg, .png, .bmp, .gif, and .ico?

PHP Code:

function getNormalImage($file){
    $base = substr($file,0,strrpos($file,'_th.jpg'));
    if (file_exists($base.'.jpg')) return $base.'.jpg';
    elseif (file_exists($base.'.jpeg')) return $base.'.jpeg';
    else return "";
} 


[Matt]

Well, for the $base line, determine what the file extension is and snip the right bit
Then, just add a bunch of if statements for file extensions.
