Photo Upload Failed (photo error)

i am using Dolphin 7.0.9.

Till yesterday, everything was working fine, but today I get this error: "photo upload failed (photo error)"

I just uninstalled and reinstalled photo module, but it still doesn't work :(

please help

Of course not, all that did was to remove all the photos from your site by removing the database tables.

Now if it was working yesterday and it is not working today; we must try to track down what changed on the server from yesterday to today.

thanks for the reply,

actually we did not change anything,  we just changed the server with the same configurations except  php 5.4 , now we are using php 5.3 as it was giving problems and we saw some post for 7.0.9 is good php 5.3

and we uploaded the TAR file and dumped the database via phpmyadmin

videos, sounds articles, blogs ,etc are working pretty much fine .

please help  , 

Yes, you did change something, you changed the php version; that is not the same configuration.  You can PM me if you like.

so what should we do now

Strange it is now .  The photo uploading is working  but still the thumbnails and photos are not displaying ,  they are seen in the albums , and when we click the View original button you can see the picture .

So please help if you can here.
