Hi there, I''m writing a little application that parses an image file and extracts the camera settings from the file (the EXIF data) and saves all the fields to the database.

The picture is stored on the file

This the the error output from wine: Invoking /opt/wine/bin/wine.bin /WIN95/westwood/redalert/ra95.exe ...

Hi, I need to take a single uploaded image file and save three resized versions of it, a thumbnail, normal and large version.
