You've yet to ask a meaningful question. You said, "Before I was trying used some code written in VTK, but it requires images files to be of the form 1 File(.1), 2 File (.2) etc. That's why I was asking whether it is possible to convert my file type (.IMG) to that.", and that really doesn't tell us anything. You need to be more specific about the current format and the format you need. All you've done so far is talk about extensions.
