Certain pictures no longer or shorter than other pictures produce a number for a filename when downloaded.
Such as "Chartier_Plantation_1" is "_20110521_1322916842.jpg"
In the German forum there was a solution to remove the extra letter 's' in a section "$newfilename = JoomFile::fixFilename($sorigfilename);" on line 897 in the upload.php. I did that and it didn't help.
Can you help? You can see this in action if you go to: http://punch-alternatives.com/punch/
Select the menu Photo Gallery, then select Punch! Houses, then the Antebellums and Plantations. Look at the Chartier Plantation and what the download says.
By the way, nice gallery!!
