How to create a Regular Expression to Validate a HTTP Image URL

by Updated July 15, 2010

Here's an example of a regular expression for validating an image url that ends with .gif, .jpg, .jpeg, .bmp or .png.

Here's the image url regex:

http://([\w-]+\.)+[\w-]+(/[\w- ./]*)+\.(?:gif|jpg|jpeg|png|bmp|GIF|JPEG|JPG|PNG|BMP|Gif|Jpg|Jpeg|Png|Bmp)$

It will validate an image url such as:

Note: The regex example was tested using ASP.NET with C#.
