Hi' im using Simple image gallery pro v 3.0.4. on:

Joomla! 2.5.11 Stable
K2 v 2.6.5
Apache/2.2.16

and am trying to upload images to K2 article galleries via the SiG pro component -> K2 galleries.
when opening the upload popup and loading a file i get a "File is not an image" error.

1.i tried enabling/disabling the Joomla FTP layer and both configs have this error.
2. also, it seems the images are saved here :
media/k2/galleries/{gallery number}
and the folders have 777 permissions

3. i tried uploading both jpg and png
