problem with image upload

[diogo]

I'm having a strange problem when uploading images. when they are bigger then 10kB (some even under it) the upload hangs in 100% and nothing else happens. The Files are present on that page directory but not added to the database. What can be happening?

edit: this is solved now.

What does your JS-console say?

[diogo]

You're right, it's a JS error

[apeisa]

Does it work on other sites on same server? Dev or stable version?

[diogo]

I have the same problem on all of them, using a multi-site installation

[diogo]

ok, this is strange... is it an error in jQuery?

Hmm, there's "500 (Internal Server Error)" from the server side (Ajax POST in your first screenshot). That's where the first problem must be. Anything in the error logs?

Anything in the error logs?

nothing...

The error I got from the server is undefined function imagecreatefromjpeg() || imagecreatefrompng() || imagecreatefromgif(), on the file ImageSizer.php

edit: ok, here a strange thing. I disabled JS on the browser, uploaded the image, saved the page, and got the exact same error. then I enebled javascript again, and the image was there on the page...

edit2: I disabled the "Display thumbnails in page editor?" option on the images field, and the uploads and was able to upload images with js enabled. Then I enabled the thumbnails option again, and had the same error, but now just by opening the page editing page. Clearly there is an error everytime imagecreatefromjpeg() and the others are called.

edit3: I was expecting already, but tried it anyway just to be sure, and this also shows the same error:

foreach($page->images as $i){
echo $i->width(300)->url;
}

edit4: one more edit. Everytime I visit the page one image is resized and an error is shown. So, is I keep refreshing the page, one more url is echoed, until all the files were created. So, the resizing works before the error stops the script.

edit5: Solved! I installed the PHP GD Library, and everything works now. Strange thing is that this problem started suddenly, things used to work before and I didn't make any change to the server... well, how do I mark this as solved?

We're nearing 12/2012 so expect unusual things happening everywhere.
