nishanth, my personal opinion is that your approach is conflicting basic web principles and concepts. The general idea behind websites is that they can deliver messages efficiently through the use of different standardized technologies to a lot of devices used by people with different needs. If you want to cycle text in your slider, do not make images of text, use text instead and style it up with CSS. It will be loaded a lot faster, it will be indexed by search engines and visually impaired people will be able to read it, too.
Maybe, in your particular case, it would be better to dump the Customizr slider and use a custom (plugin) slider that could feature yout texts and/or images in a more suitable way. This way you could control all that first-page real estate you are now wasting for images of unindexable text.
