add images to wordpress website

We need six animations images in CSS/JS format - files with business images to insert in our website – Each image should be 960px x 150 px. These images should provide an area for one line of text of – approx. 50 characters – that will be shown in motion at a predefined speed. Provide a way where these two parameters can be adjusted (I will provide text and from time to time I may modify it). At least three of the images will be built using screen captures of my application “Manager” which I will provide (You search and suggest (for my approval) the other three business images that you consider appropriate). See attached samples. The images will be used at the top of the first page in the existing website [login to view URL] and next project web site [login to view URL] that will be built (hopefully with your help). The existing [login to view URL] and future website are built using wordpress under PHP and MYSQL.
