It seems that this is a very common problem. From the materials read by laogao, two solutions are summarized:

Step 1: Determine the crux of the problem and start-> Run. In the run input box, enter "regsvr32 c: \ windows \ system32 \ pngfilt. DLL "(then click OK). At this time, two prompts may be returned, which has different solutions.

 First, you have successfully registered and installed IE6. The possibility of registry problems is very high. Registry issues. To solve the problem that IE does not display PNG

Method 1:
1. Open the registry and expand it in sequence.
Hkey_classes_root \ mime \ database \ content type \ image/PNG
2. Change the value of the extensionkey to .png.
3. Find the image filter CLSID key and change the value
{A3CCEDF7-2DE2-11D0-86F4-00A0C913F750}

Method 2:

If the displayed file cannot be registered or found, the problem is that the PNG display is controlled in IE.Pngfilt. dllFile loss or version error. The solution is:

DownloadPngfilt. dllCopy the file to the System32 folder and the System32 \ dllcache folder at the same time. Otherwise, the original file in the System32 \ dllcache folder will be restored continuously. Then, enter "regsvr32 C: \ windows \ system32 \ pngfilt. DLL "(then click OK) to register againPngfilt. dll,
If you are using IE6, the operation ends here;
If you are using IE7, proceed to the next step and downloadPngfilt. dll, Overwrite the original IE6Pngfilt. dllFile, note that both folders must be overwritten, and then the problem is basically solved.

Summary:

There are many reasons why ie cannot display PNG images, but basically it is pngfilt. DLL file registration problems or installation of QuickTime or other software causes pngfilt. the DLL is replaced with another version, so you only need to use the correct pngfilt. DLL file version overwriting can solve the problem.

In the solution, the reason why IE7 needs to be overwritten is that IE6's pngfilt. DLL files can be directly registered, while IE7's pngfilt. DLL files cannot be directly registered. Therefore, you must register with IE6 and then use IE7.
