Why do pictures always appear as big red crosses when I open a web page?

When I open the computer webpage, the picture always does not show up and there are many big red crosses. What is going on?

1. Copy pngfilt.dll from a computer that displays normally, then run it in the start menu and enter:

regsvr32 c:\windows\system32\pngfilt.dll

After inputting, press Enter.

2. Start -> Run, enter "Regedit" in the run input box and press Enter. Go to this path "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\Accepted Documents", right-click on the right "New" -> "String Value" and then name it with the largest number. Here it is 3, so it is named 4 , and assign the value to "image/png".

3. Open the registry [HKEY_CLASSES_ROOT\MIME]. Under normal circumstances, there are several major items in it. When you cannot open png format pictures, there is only the Database item. Under normal circumstances, there are hundreds of items under the Database item, but under abnormal circumstances there are only three or four items. This can be done by copying the MIME key registry from someone else's normal machine (xp can be copied from vista) and importing it on your own machine. Sometimes there is a problem with MIME permissions (such as empty permissions), you just need to delete them all and then import.

4. Clean up the junk files in the system, refresh the web page several times, and install the latest Flash plug-in.

5. This is a typical phenomenon where the network is extremely slow or unstable. Find the cause of the network line. The problem must be with the router. You can reset the router and broadband modem and then reset the parameters.

6. Open IE browser, Tools, Internet Options, Advanced, and check Show Pictures. Or right-click the image that cannot be displayed and click Show Image.

7. Maybe the firewall prohibits the image display function, try closing the firewall.

8. Use 360 ​​Security Guard to repair IE and then kill the virus.

9. Modification of the HOSTS file often leads to similar problems: File location C:\WINDOWS\system32\drivers\etc Open hosts with Notepad, clear the content, and keep only the entry 127.0.0.1 localhost. Close and save.

10. Open "Run" and enter -> cmd -> Enter and then copy the following line of characters into the black cmd box and press Enter. Wait for all the dll files to be registered and then close them (the following is the code to be run) ： for %1 in (%windir%\system32\*.dll) do regsvr32.exe /s %1

11. Use 360 ​​Security Guard to scan for malicious comment plug-ins and remove them.

12. If there is a problem with the computer system, just reinstall the system.

What’s the matter with the red cross in the picture on the webpage

2. Click [Tools-Manage Add-ons] on the main page of the IE browser, and then check whether the shockwave flash object (ActiveX control) is enabled in the window that opens. If it is not enabled, just enable it. After starting, restart the computer, and then install shockwave flash object (ActiveX control) according to the system prompts. as the picture shows:

3. Lower the security level of IE browser to medium or low. Click [Tools-Internet Options] and switch to the [Security] option to adjust the security level. Continue to click the [Custom Level] button and make the following settings. as the picture shows:

(1) Check all options of [NET Framework] to enable them, and check [Active Control Automatic Prompt] to disable them;

(2) Check "Initialize and script run Active controls not marked as safe" and select enable;

(3) Check "Download unsigned Active controls" to enable it.

(4) Check "Don't prompt the user to make a selection when there is no certificate or only one certificate" to enable.

4. Upgrade the computer’s flash player level to the latest version. If the above method still doesn't work, just uninstall IE first. Then download the latest version of the browser. After downloading and installing, the problem is basically solved. Of course, the most rogue method is to reinstall the computer, which is a last resort.
