447746 PHP: Small fixes

Hello scripters! Someone made a large script for me, and over the course of a few days I've been testing it and I came across a few errors that I need to have changed. I can't get ahold of him to fix it for me so I'm posting a new project to have it changed. Don't think anything big.. It's very simple. I just can't find it. For example, somewhere along the script you need to upload a picture. If the extention of the file is .JPG (caps) it wont display it (because the server runs linux) and somewhere in a textbox if you fill in anything with " or ' it won't save it either. Furthermore a few fields need to be marked as "required" to fill in before it saves. P.S: Don't ask for millions of dollars for this, it'll most likely cost you less then an hour to do. I'm not stupid. Stupidly high bids will be removed. P.S: I don't need automated and unpersonalised messages. Start your bidding with the text LSVM or I wont pay attention to it (because I'll know your automated, duh)
