Using WWF 7.01, with SQL Server. When I try to add certain images into a post that have a url not starting with WWW, they are often changed resulting in a broken image. The URL below is an example: http://i.imdb.com/Photos/Ss/0120742/6 - http://i.imdb.com/Photos/Ss/0120742/6 After I post, and I look at the HTML source, it has been changed to: http://i.imdb/Photos/Ss/0120742/6 - http://i.imdb/Photos/Ss/0120742/6 It leaves the ".com" off the post. Anyone else have this problem and know of the fix? Thanks.

Upgrade to version 7.5 to fix the problem.

For security reasons images must have a web standard extension for a graphic like:- .gif .jpg .png .jpeg If an image link has any other extension it won't be excepted by the filters it could be a link to a malicious script or file that could be used by a hacker. ------------- https://www.webwiz.net/web-wiz-forums/forum-hosting.htm" rel="nofollow - Web Wiz Forums Hosting https://www.webwiz.net/web-hosting/windows-web-hosting.htm" rel="nofollow - ASP.NET Web Hosting |

It looks like the forums thinks that everything after .com is the extention to the file. That's why it is chopping it off. Allowing people to post a (supposed) image with *.com or *.exe extenstion is a BAD idea. Those are executable files and any Windows computer will try to execute (i.e. run) them as a program instead of displaying a file. And allowing someone to post a (supposed) image with no extention (like your links) is also a danger since it is possible to redirect that to anything, including an executable program. For security reasons, all images must have a valid extention like *.gif, *.jpg, etc. Othewise you are opening yourself up to malicious files being uploaded instead of images. ------------- http://www.wistex.com" rel="nofollow - WisTex Solutions http://www.caribbeanchoice.com/forums" rel="nofollow - CaribbeanChoice Forums |
