Match any image insert in a tag . simply replace the .jpg in the pattern whit a variable of content type ex:.swf,.js,.gif and loop the pattern to retrieve all tag whit the contenttype pass trought.... Very useful when you have people uploading html document in your site and you want to retrieve all dependecy.

Use this along with this replacement string <img\1 /> to convert image tags to XHTML compliant image tags.

easy when you want to allow your users to post images, but in a controlled way. I used it like this (in php): $text = preg_replace("/(\[IMG\])(\S+?)(\[\/IMG\])/is", "<a href=\"\\2\" target=\"_blank\"><IMG SRC=\"\\2\" align=\"center\" height=\"100\" border=\"0\"></a>",$text); so whenever they use [img]http://www.foo.com/bleh.jpg[/img] it will be converted to <a href="http://www.foo.com/bleh.jpg" target="_blank"><IMG SRC="http://www.foo.com/bleh.jpg" align="center" height="100" border="0"></a> so you get a 100 pixels high picture, and when they click on it it opens in a new window... (to prevent users from posting huge pictures and stuff)

Matches HTML image leaf filenames.

This expression will return the src (source) property of an image tag <IMG>. The source returned is limited to the file extensions supplied. It doesn't matter if the image is prefixed with '../' or 'http://..blah' or 'drive\path' or nothing. This expression could be modifed to return other sources or for the tags (ie <BGSOUND>, <SCRIPT>, etc.) depending on the file extensions given. I needed this to replace the source of images in a HTML page when I wanted to save the page to a local drive and keep the images intact. If anybody could modify this further to include only the <IMG> tag, I would appreciate the effort.

This expression matches valid image URLs. The main use for this would be in UBBC tags. Written by RyanJ and Jick for FWD (http://flexwebdev.thenamesdan.com/)

This regular expression allows you to match all image tags

This is a derivation of a few other image tag regex patterns I found on the site that didn't seem to work. This is my first regex, so if I did this wrong - apologies in advance! It works for me...

My second ever regex - a derivation of an image tag pattern, use in conjunction with <[iI][mM][gG]([^>]*[^/>]*[/>]*[>]) to remove advertisements from RSS feeds. Whee!

Gets the image url in an HTML <IMG> tag.

This is a Microsoft .NET/Mono regular expression that can be used to find the address of an embedded image inside an HTML email body. The address will be the 2nd group found in the match.

It searches for a IMG tag and group information about source of image.

This pattern matches an image url attribute of an img html tag. It searches for the src attribute and grabs the value as a grouped match - "imgSrc".

This expression should work to validate that an uploaded file's extension is either jpg, gif, or png.

This regex is good for finding image tags without alt tags. I used this for working on Section 508 compliance. This is a M$ flavored regex and probably won't work with anything else.

Nice for checking local filesystem relative pathing. I used it for testing in php scripts that work with images.

Great for extracting out all the image src attributes.

A nice little regex to verify a URL pointing towards an image. Can be useful.

This expression will capture font tags(or any other HTML tag if you change the word font in the expression) with parameters and stop at the closing font tag bracket. The only keyboard characters it will not find between the starting and ending bracket are additional brackets. So for example if you are looking for image tags it will not find <img src="..." alt=">My Picture<"> due to the nested brackets. When I allowed nested brackets like this the expression did not always return only the tag I was looking for. Sometimes it returned additional tags at the end so I suggest staying away from brackets in alt text and anywhere else you may be allowed to do it.

This regex will match all HTML tags except 'a' tags or 'img' tags. You can edit the list of exclusions as you see fit. I use this regex to strip all HTML tags from source data except anchor tags and image tags.
