The images must fit uniformly in the areas they're being placed and they must all be the same size. The images we have are not a uniform size, but we've dealt with that before with our work for the Sir John Golding Centre.
Take a look here: http://sjgrc.com/ - We used color and blur effects to make images that were differing sizes into the same size so that the images in the slider were displayed professionally.
Please let me know if you can do something similar for me today within the next few hours. No upfront payment please. Payment will be given only after task is completed successfully.
