Joomla Recaptcha reinstallation and change 2 graphics

We have 2 exisiting websites [login to view URL] and [login to view URL] and we had a Recaptcha installed for the contact and registration pages. As it turned out the images were never shown up and we de-installed the extension. Since then whenever people try to register on the website after they click "ok" the screen just turns white. Please test before bidding for the job and write "TEST" in your bid. We need..... 1. Install a working Recaptcha for the contact page of both the www.ie-academy and the [login to view URL] websites ( i am getting about 50 spam contact messages a day!) 2. Change this graphic [login to view URL] and this graphic [login to view URL] simply by changing the telephone number to this one ..... 026029196114 for both of them. The graphic should be very very similar to the original and the size of the graphic should fit the frame. 3. Make sure the registration forms are working and people can register to both websites (which is currently not possible) I have the log in details and i will give these to the lucky person.
