Customization - Transfer to PayPal page

1.
Hi there:
Firstly thank you for such a great theme. Just what I was looking for
Just a couple of things - and I don't know if the issue can be resolved.
Having clicked on preview ad and then continuing on to PayPal the end user is presented with the attached screen shot. It will not do anything until the OK button is pressed.
Is there...
A way to by pass that page and take the user directly to PayPal?
A way to customize the look and "feel" of the page if the above is not possible?
Hope you can assist me.

2.
Just a quick inquiry, hope you will answer it this time.
Do you (or can you advise me on somebody that could) undertake a customization to this theme?
It relates to the sizing of images (GD or magemagick) when uploading them?
Thanks,
Chris
