in your inc_functions.asp, in the ReplaceImageTags function find this section of code:

 					strUrlText = replace(strUrlText, """", "") ' ## filter out "
					'## Added to exclude Javascript and other potentially hazardous characters
					strUrlText = replace(strUrlText, "&", "", 1, -1, 1) ' ## filter out &
					strUrlText = replace(strUrlText, "#", "", 1, -1, 1) ' ## filter out #
					strUrlText = replace(strUrlText, ";", "", 1, -1, 1) ' ## filter out ;
					strUrlText = replace(strUrlText, "+", "", 1, -1, 1) ' ## filter out +
					strUrlText = replace(strUrlText, "(", "", 1, -1, 1) ' ## filter out (
					strUrlText = replace(strUrlText, ")", "", 1, -1, 1) ' ## filter out )
					strUrlText = replace(strUrlText, "[", "", 1, -1, 1) ' ## filter out [
					strUrlText = replace(strUrlText, "]", "", 1, -1, 1) ' ## filter out ]
					strUrlText = replace(strUrlText, "=", "", 1, -1, 1) ' ## filter out =
					strUrlText = replace(strUrlText, "*", "", 1, -1, 1) ' ## filter out *
					strUrlText = replace(strUrlText, "'", "", 1, -1, 1) ' ## filter out '
					strUrlText = replace(strUrlText, "javascript", "", 1, -1, 1) ' ## filter out javascript


add the following to that section:

					strUrlText = replace(strUrlText, "vbscript", "", 1, -1, 1) ' ## filter out vbscript
					strUrlText = replace(strUrlText, "mailto", "", 1, -1, 1) ' ## filter out mailto

@Rasco
Aber nur wenn du in Deutsch schreibst

@Richard Kinser
by the way....

strUrlText = replace(strUrlText, "vbscript", "", 1, -1, 1)
Over 80% are using IE, so don't forget to disable VBS!!

the other problem with that Richard is that ther arequite a few different ways of writing vbscript and jscript which would fool your replace function

Yes, but I gues the rest of the function will filter the & and # I gues, so it wouldn't matter

Instead of filtering out those other characters, why not just convert them into their HTML entities. For example & would be converted to &#38.

Then when someone tried to put in javascript: It would become javascr&#38#x69;pt: which to the browser would just be javascript: instead of javascript:

strUrlText = replace(strUrlText, "mailto", "", 1, -1, 1) ' ## filter out mailto




I haven't got any code like that in ReplaceImageTags function in inc_functions.asp with version 3.3.03, is this for Snitz v4?
