Solution 1

It doesn't work because strings are immutable. For instance, the input.Remove() method doesn't change the input variable content, instead it creates a new string instance (that you are discarding).

change from

Quote:
input.Remove(start, (endi + 1) - start)
input.Insert(start, "src=cid:image001")

to

VB

input = input.Remove(start, (endi + 1) - start)
input = input.Insert(start, "src=cid:image001")
