IE wants to download png's

Everytime I click a png in a web page IE tried asks me to save the file to disk instead of displaying it.  Its because I made the mistake of installing Quicktime and then removing it wrong, now I can't show png's.  Anyone know what I can change in my registry to get pngs to show properly in IE 5 on windows2000?

What keys related to png are in your
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer

I think I delete a png entry cause it referenced quicktime.

Thanks

try to reinstall quicktime again adn then perform a standard uninstallation. This is repeat the impropwer uninstallation earlier.

If you have problem doing that i would suggest that you try to install ie5.5 sp2. even though you might find it unnecessary, but ie5.5 has the repair feature where it will identify any problem with the previos ie installation and repair it. Check out from microsoft.

IE 5 on windows will not show PNG files without QuickTime. (In fact im not even sure 5.5 or 6 will show them.).

I can't or don't want to install Quicktime or upgrade IE, I need a fix.  Can someone check if they have a png entry somewhere under

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer

?

Thanks

Find a png file on your computer.  Hold down the shift key.  Right click the file.  Select "Open with".  Highlight IEXPLORE.EXE (or Internet Explorer if it is written that way) in the programs choice.  Tick the box that says "Always use this program...".  Click "OK".  Job done.

There won't be an entry under Internet Explorer (at least there isn't on my PC).  It will be a variation of settings for the ".png" extension.

I find I can't open a local .png file on the harddrive. I've tried in Win98SE, ME, and 2000.

Strange, in Internet Explorer, if you choose File>Open, and click the drop-down menu to change from html, you'll see png (and others) in the list.

Even right-clicking and choosing Internet Explorer, the graphic opens in the associated program, not IE.

I'd suggest everyone give it a try and post back with the results. Maybe there is no fix.

Associating the png with IE doesn't do it.  My IE still asks to save the png to disk even when I try to open or view a png file locally.

They do both support PNG files from version 4 browsers but not very well.

Use W98SE, IE 5.5 w/sp2, no problems with having two defined apps to open png files, selecting and/or using open with.  

This is interesting in this regard.

Afterthought, recall one of my browser upgrades taking me to a backlevel of vrml related controls, and WindowsUpdate helped to resolve it.  Multiple reboots and revisits to WindowsUpdate after loading the increments in a specific upgrade.  May also help you.

Good luck, and "hi" all.

What do you have installed on your system and defined to be the default program to handle png file types?  Many applications support this, such as Fireworks, Dreamweaver, MS Picture It! 2000, and a number of others.

Hi Asta,

I have Fireworks, ACDSee, and Slowview asssociated with the .png format on my 3 operating systems. I'm running IE6 final and IE5.5 Servcice Pack 2.

Do you think if there was no association, IE would open them?

You said using "open with" wouldn't work right?  The more I look into this the more I see that IE does support .png files.  You have show pictures ticked in properties right?

Did you check your support for .png at the bottom of the page that Asta gave you  a link for?  I am assuming this prompted you for a download.  What about object and embed options?

I think you might want to install IE again over the top of itself.  Or try reinstalling software that does support .png and then try the "always open with" steps I said before.  It sounds to me like somehow your .png support has been corrupted.

Good morning, all.

Interesting, indeed, reghakr.  Using W8SE, IE 5.5 SP2 and had uninstalled NS.  But tried this and results:

Changed png files to be opened by default with IE, result was no image, but launched in IE (settings correct to display images and all multimedia files, but only placeholder box resulted).  This "may" be attributable to the odd issues found in IE 5.5 SP2 in terms of the plug-in support, etc.  Can't get IE in this environment to display png files (5.5 sp2).

Changed png files to be opened by default with Dreamweaver, invalid file type on a few selected (new).

Changed png files to be opened by default with Fireworks, opened fine within Fireworks.

Thinking ...  baffled.

Asta, I was wondering if it may be related to the plugin support myself. I even tried adding the MIME format to this key:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Accepted Documents

My 98SE (IE6) machine shows a MIME type of image/x-png
My ME (IE5.5SP2)machine shows a MIME type of image/png
My Windows 2000 (IE6) machine shows a MIME type of image/png.

And why is it in the drop-down list of files to open? Even more baffling!

Hi, reghakr.

This has been really strange.  I think you're right, though, on the plugin.  I downloaded/installed the IE 6 final version last night, ran SFC, noted all the dlls deleted such as Real plugins, etc.  I'm noticing some other odd results and still tracing, found this of interest and relevant to the png issue (the first the lack of transparency I noticed on transparent png files):

http://support.microsoft.com/support/kb/articles/q294/7/14.ASP?LN=EN-US&SD=gn&FR=0&qry=ie%206&rnk=4&src=DHCS_MSPSS_gn_SRCH&SPR=IE

Another anomoly I noticed after the IE 6 upgrade was that IE opened my Office docs:

Office Documents Open in Internet Explorer
http://support.microsoft.com/support/kb/articles/q162/0/59.asp?LN=EN-US&SD=gn&FR=0&qry=ie%206&rnk=9&src=DHCS_MSPSS_gn_SRCH&SPR=IE

_________

More research to do, but wanted to add that I received a Critical WindowsUpdate notif this morning, but cannot access.  I'll check my file type alignments as well.

Afterthought.  Not Prompted to Specify Download Folder for File ... you may have already gone through this process, and in your case you'd want to accomplish the reverse by assigning IE as the default program to open png file types (all found), then taking the action here:  IE 4 definitely didn't support png file types within IE, but trying to verify which versions do.

http://support.microsoft.com/support/kb/articles/Q177/9/76.ASP?LN=EN-US&SD=gn&FR=0&qry=png&rnk=3&src=DHCS_MSPSS_gn_SRCH&SPR=IE

Even with IE 6, after configuring IE to open png files types, image does not display .... only placeholder equivalent despite settings verified correctly.

-----

Unlike yours setup for 98 and IE 6 (MIME type of image/x-png)

Mine which is W98 Second Edition with IE 6 final has
image/png but descriptor is Macromedia Fireworks Doc.

Meetings today, but will check further when I can.  Baffling.

16.1 Platform/Browser Support
PNG was designed to be network-friendly, so naturally it is recognized and supported on all platforms. PNG does not enjoy universal support by browsers, however, particularly by the Big Two. Initially, in Navigator and Internet Explorer, PNGs could only be handled as embedded objects (placed with the <embed> tag) and viewed with plug-ins such as PNG Live. Eventually, PNGs became supported as inline images (placed with the <img> tag, like any other web graphic) in Navigator 4.04 and IE 4.0, however, they do not support alpha channel transparency or gamma correction without an additional plug-in.

http://safari2.oreilly.com/table.asp?bookname=wdnut&snode=142

----

I have no problems ever viewing embedded png files within pages, only png files on my system or image types are the problems.

Final update for today:
This link ...  http://www.libpng.org/pub/png/

displays the png fine, checked the source and isn't imbedded, standard href.  Right-clicked/saved the png image to desktop, IE default for png.  Their source defines image/png.  When I then double click the saved png file, only block displays in IE 6 windows.

YAY!  Success!

Finally, I can display the downloaded and online *.png images using Windows 98 Second Edition, IE version 6 (final release).  This is what I did following the earlier information:

Was able to update again with WindowsUpdate and downloaded the Critical Update (again, which appeared to have been overwritten from the browser upgrade)/installed/rebooted.

Checked adobe's site and tested my Adobe Viewer ... tested fine, that plugin/viewer wasn't altered, still functional and tested well.

Downloaded Quicktime version 5, installed the plugins, rebooted.

Tested all, and all is now excellent and viewing in IE 6 without a hitch.

Did you also (after upgrading to IE 6 final), download/install the QT 5 version?  I was most careful at download/install time to not allow QT to modify any file type associations other than the Mac-related environments and png worked well, after closing and rebooting.

Most of the answers and help here is useless too me because I can't upgrade IE and won't install quicktime.  I just thought there was basic png support in IE 5.0 and wanted to know what settings were required to make it work.

How do I distribute the points across several people evenly?
