Replace Chacarter in Dynamic URL

How to replace a chacarter in dynamic url

[Sgroove]

Hello, I'm new in the forum.

This is my issue.

I have images URL pulled from XML feed.

The image URL is:

www.domainname.com/files/1234567123456/1234_h.jpg

and I want to internally replace it with:

www.domainname.com/files/1234567123456/1234_g.jpg

basically the _h at the end of the URL becomes _g

This should happen before that the images are loaded..

Any idea?

Thank you very much

Are the images on your server, or some other?

not on my server

Place a rewriterule on the image-hosting server to accept requests for your modified "g" URLs and rewrite them to the correct "h" image filepaths.

Since the requests are going to the image server, the code must be located there.
