[Rails] Image upload problems

There as until recently (0.9.2, I believe) a bug in the MySQL driver, 
which would cause binary data to be corrupted when transferred to 
MySQL. Make sure you're on the latest version.

Another thing to check: Make sure your BLOB field is big enough. 
Mediumblob holds 16Mb, so that should be alright.

Finally, I noticed this in your code:

>    @params.delete("photo" => "tmp_file")

This shouldn't do any harm, but I'm not sure what good it does, either. 
What did you intend it to do?

>       redirect_to :action => "show/" + @photo.id.to_s

This can be tightened up a bit, by saying

redirect_to :action => "show", :id => @photo.id

Good luck,
