Preview/Thumbnail View

[TRS80]

I'm 98 SP1 user and several months ago reinstalled the entire system, so its pretty much clean. I've lost the ability to preview thumbnails in the left hand pane of only JPGs. BMPs, GIFs, etc. are displaying fine. After researching several MSKB articles, the problem was addressed as thrd party software might adjust file type associations. This problem started when I started used Desktop Architect (theme creator). The MSKB articles suggested several registry hacks yet it seem to address such a problem would be related to all graphics files, yet my problem is only with JPGs. I didn't feel comfortable with MS's suggestions since it was only for a select graphic type. The MSKB articles indicated I should be of a certain level of upgrades and have ciritical updates installed, which I do. Also, I have always been in IrfanView graphics viewer user and this "third party" program has never been a problem. Of note, I have no other major problems other than one I'm going to address under separate cover. Any suggestions to get JPGs to preview properly?

The first thing to try;
Go to Start>Run, and type:
regsvr32.exe thumbvw.dll

Then shutdown and restart.

If that doesn't work, here's a vbs script that works very well:
open Notepad and copy and paste the following between the lines and save the file as RepairThumbnailView.vbs. Double-click on the file repair the preview

Thanks for your response regarding the Preview/Thumbnail problem with JPGs. I tried the Regsvr32 command and the VBScript, neither of which worked. They both sounded promising. I also tried another Regsvr32 command with shdoc401.dll, as suggested by another and it didn't work either. I also referred to several MSKB articles regarding CLASIDs and everything appeared normal. Any further recommendations are appreciated.

Did you get the Confirmation dialog box?

Try this:
Go to Start>Run, type regedit, hit Enter. navigate to HKEY_CLASSES_ROOT\.jpg Make sure there is a ShellEx key below, and below that a key named {BB2E617C-0920-11d1-9A0B-00C04FC2D6C1} When you click on that key, the (Default)Data should be {7376D660-C583-11d0-A3A5-00C04FD706EC}

and also this to restore the default .jpg association;
Open Windows Explorer, go to View>Folder Options, click the File Types tab. Click New Type...

Type Jpg for Description of type.
Type .jpg for associated extension.
Type open under Action.
Type "C:\Progra~1\Intern~1\iexplore.exe" -nohome for application used to perform action.
Click the use DDE check box.
Type "file:%1",,-1,,,,, for DDE Message.
Type IExplore for Application.
Type WWW_OpenURL under Topic.
Click OK, Apply, OK.

If the .jpg extension already exists, just modify the entries as shown above.

Yes, I did get the confirmation box for the VBScript on your previous recommendation. In your latest, I checked the Registry key (as I also saw on the MSKB) and all was well ther too. But at last I checked the File Types, which I had before, and never noticed that the IExplore info for the JPG had lost its DDE data. I added the info you suggested and also check Enable Quick View and everything seems to now work properly for Thumbnails. I imagine a graphics program I had used clobberred some File Type data. I haven't rebooted yet but I'll let you know of that screws something up. Thanks for your time and input. BTW -- Did you notice my other posting regarding my loss of the ability to use <Ctrol-Alt-Del> to either reboot or shut down programs? I'd like your input on that too.

Thanks for replying back with the info, this may help many others.

Sorry, not sure abot the Ctl_Alt_Del problem. Had this occur with Win95, but not Win98.
