Topic: Pictures not showing correctly

I am using Porta with Simpleviewer and everything seems to be working correctly except one thing. When I upload the Porta files into my site the picture aren't showing correctly - when I press the small picture to see the bigger picture (ex. 001.jpg), it actually opens another picture (ex. 002.jpg). The numbers/files in my FTP folder seem to be correct - small 001.jpg is the same as big 001.jpg.
