what is a good regex expression for remove html <img ....> tag?
I tried
"<img [/:.a-z =0-9\""_;&]*\->", RegexOptions.IgnoreCase)
but it is not quite working

thank you for your time

Why not simply "<img[^>]>"?

thanks for replying. However I found this worked better for me

myregex = New Regex("<img .*?(>|(/>|(</img>))",
RegexOptions.IgnoreCase Or
RegexOptions.ExplicitCapture)
It does not gobble up other tags fooling the <img .....> on the same line.
it also supposed to take care of xml also

Credit is due to Dave Sexton for helping arriving at the above expression

There is never ever an ending tag for the img tag, and even if there
were, your pattern doesn't handle that.

So far I have not seem ending tag for <img ..> at least for html.

although I think I have sees some comments of XML <img tags and <object tags
both have ending tags of sorts

I did made mistake in thr regex for the ending tag by leaving out one right
paranthesis

myregex = New Regex("<img .*?(>|(/>)|(</img>))",

Yes, but XML is a completely different thing. There the tag name "img"
has no special meaning at all.

It still doesn't handle the ending tag, if there ever was one. As the
starting tag ends with ">" that will be caught instead of the ending tag.
