misc. adjustments to php/mysql simple image hosting script

I am near launching an image hosting service using the script from scripteen: [login to view URL] I have heavily modified the visuals and templates but need help with a few remaining items.? Initially I will need: -the registration page, once registered the page goes nowhere.? It says registration is successful and that is it.? I need it to say it was successful and redirect the user to the login page. -The current browse button to browse and upload an image is? input type="file", i have an image i would like to replace the button with but not sure if this is possible and would work across IE/firefox etc. -on the main gallery page when the page loads it seems to jerk a couple pixels to the left on page load, not sure if this can be fixed so the page loads without moving around. -on the users own gallery page i want it to list their image thumbnails by default (currently it does not show them unless you tell it to).? I also want the thumbnails to be resized to 60x60 max. -possible additional jobs would be -how well can this script scale, for example does it need to be coded so that when a folder of images hits a threshold a new folder is generated? -security vulnerabilities in the code, I will be wanting a security audit of the code to make it hack proof as possible. I need this done asap.? I had someone lined up but they put me on hold for a week.? I am wanting to get this done in the next couple days.? -fyi I am in New Zealand but usually find a way to compensate for any time zone communication.?
