I have string that is an HTML page from my DB. What I want to do is search through the string and get all <img tags that have the height or width set, and change the src on each of them. I am not very good with Regular Expressions so I was hoping someone out there could help me out.

Hi johnywhite;

Can you post some actual samples of the img tags?

Also:
Will the height always come before the width or the other way around or in any sequence?
Will there be other attributes with the image tag? if so what order will they be in respect to height and width?
Is the part of the source that will change be the same and will the replacement be the same?

In order to do what you want the exact pattern of what must be changed must be known and what to change must be known. So can you give a specification.

Thanks;
Fernando
