Hi,
today I installed the newest version of Zenphoto on my Apache web server.
When I try to upload a picture (jpg or png) jQuery uploader reports an error `Error: Filetype not allowed`
The size of the picture is 100kb, so that shouldn't be a problem.
Uploading with http gives the error:
`You have attempted to upload one or more files which are not Zenphoto supported file types`
After it shows the error, the page gets redirected to `Your files have been uploaded.`

I'm using Firefox. IE shows the same error messages.

I do not have GD installed. ImageMagick is installed, but I'm not sure it is working/configured.
Do I need GD to upload jpegs and so on?

I checked debug log, it's empty. The security log shows the following every time I open an album:
`2013-04-12 13:44:02 My-Ip-Address Album-access admin MyName Blocked /zenphoto/zp-core/admin-edit.php?page=edit&subpage=1&tab=imageinfo&album=new-album&uploaded=1&albumimagesort=id_desc`

The outcome in the security log shows only "success" when I login, when I access an album or upload photos it logs "blocked", but I don't get any other error message apart from the "Filetype not supported" one.

I'm using https with a self-signed certificate. Is that maybe an issue?

Problem solved. This topic can be closed.
The problem was that I had not activated the GD library in PHP.
I just removed the ';' in front of "extension=php_gd2.dll".
Then restarted Apache and checked phpinfo().
It was loaded and then suddenly everything worked fine in Zenphoto.
So far everything is solved

I do not have GD installed. ImageMagick is installed, but I'm not sure it is working/configured.

The problem was that did not have any graphics libary enabled Zenphoto supports. ImageMagick is only supported via the Imagick extension. But GD is generally fine.
