This happens when web developers are not paid well
The contact us form of this website is in IMAGE form. www.omjewellers.in/contact_us.html Awesome ! Well spotted. Made in 2012, so it's not like they are working on it now.
Note that their splash page is made in flash. In 2012 ? ... mmm.. bad. Btw the way Om Jewelers is in the top 3 ornaments maker in Mumbai. But don't now why they are not getting there site done. Looks like an example of cargo cult design to me.
