Does the WS500 somehow prevent PHP image resizing when visiting a website?
I have a few websites that we visit which have featured articles on their homepage. The featured article will have a synopsis paragraph about the article along with a thumbnail image - resized via PHP. The image placeholders where the thumbnail image is supposed to appear has a box with a red "X". But if you click on the featured article(s) to view/read the entire article it has the full size image of the same picture. It shows up with no problems.
If I leave our network and go elsewhere to any other PC - we do not have this problem. The only difference is we are filtered by SOPHOS WS500. I have setup a new policy for a test account to allow all categories and even put the website as a TRUSTED site - so filtering should be minimal if any at all while visiting this particular site. So it really has me puzzled. The only other thing I could think of it might would be is the fact we are also using SOPHOS Endpoint Security and Control. But I have one PC that does not have that software on it yet and it does the same thing - shows a red X.
I then thought it might be an issue with Internet Explorer. So I put the website in question as a trusted site in Internet Explorer as well as setting the security and privacy settings to the lowest setting - allowing anything/everything and still get the red X.
So I am wondering if the Sophos appliance (WS500) is seeing the PHP image resize happen and blocking it for some reason?
If I go home to view/visit the website - it shows up normal with no problems. Called a friend and had them pull it up at their office and they say it pulls up normal with no problems.
Really, really puzzled.
If I go into the Sophos appliance reports - it does not show anything blocked visiting the website. Which it should now anyway because in the WS500 appliance it is now categorized as a trusted site.
HAS GOT to be something to do with the appliance.
ON EDIT:
Furthermore, if I view the source code of the website and get the URL of the image to be in the imageplace holder where the red X is and paste the URL into my browser I got HTTP 404 Page Not Found error. If I copy and paste the same link and email it to my friend - he can click the same link and it pulls up the image with no problems.
Here is one of the links:
On our network if you visit this website the featured articles on the homepage - the image place holders have a box with red X. But if you click on one of the featured articles - say - Addictions - Alcohol and Substance Abuse - the picture inside the article which is full sized is displayed correctly. It is just the thumbnails on the homepage that are not showing up correctly.
So for this article - the thumbnail link is: http://www.mentalhelp.net/common/classes/thumbnails/show_image.php?filename=../../../images/root/alcohol2.jpg&width=45&height=45
If I click on the link I get a page not found error. Anybody else who clicks on it sees the image.
