Author Topic: ThumbNails No Longer Show Screenshot, Just Generic Flower Icon (Read 20123 times)

dbareis · « **on:** September 15, 2021, 04:33 PM »

Except for one image which I added boxes and text all icons are generic flowers and not a thumbnail of the captured image. Modifying another image didn't make its thumbnail appear.

I capture as ".PNG", if I put ".JPG" into the capture directory these show up OK, the image that shows the thumbnail is a ".PNG" like the others that don't.

I only noticed this yesterday but have made no option changes in the app. If I go to the directory in explorer I can see ALL of the thumbnails correctly so it doesn't appear to be a Windows issue.

The only thing image related I have done recently is fix the mime type for JPEG images as shown here: https://nspeaks.com/...if-heres-how-to-fix/

I have tried putting that back to the original JFIF value and restart the app but that doesn't fix it. Also why is that one lonely image OK?

Can you try restarting windows and see if it fixes it? SC relies on windows to do the heavy lifting of showing thumbnails and occasionally gets stuck making them and a reboot fixes it.

I'd rebooted before but that didn't fix it. Just did it again and was about to say it didn't but was showing more than before, but a few more turned up as I scrolled. Quite a few still appear to be "stuck". Explorer shows icons for all images. I think you cache them but perhaps also cache failures? I stopped and restarted the app and this time all but 3 of 711 files show correctly (at least those in the current capture directory, not so great in subfolders though).

Should Tiles overlap making it hard to select the next one? I haven't noticed that before either (on long filenames)?

I think I found the problem, I used to have "Tick Auto Move Older Screenshots, set to x days" ticked but just found it unticked, I don't believe I did that.

It seems that around 700 is the upper limit you want in a directory even on a powerful 12 core computer with 32 GB RAM. Maybe instead (or along with) a number of days option there should be a count of files option: Tick Auto Move Older Screenshots, set to x days, or y files

And maybe that should run periodically or after every capture and not just at startup.

Hi, same problem here since one month back. Tried your trick with auto move but no joy.

Fribytare · « **Reply #5 on:** October 08, 2021, 02:33 PM »

Changed to JPG and got a thumbnail on the next capture. Changed back to PNG but no thumbnail on the next capture.

Edit: This solution only worked a few days. Maybe only to the next reboot.

I fixed the problem by following the instructions linked in another thread.

You could try the "nuclear option" and rebuild the thumbnail cache, that might clear out something - instructions here.

My auto-move improved things but I still have a few turn up, I will try the "nuclear option" mentioned earlier.

dbareis · « **Reply #8 on:** October 12, 2021, 02:17 AM »

The "nuclear option" instructions aren't complete and I had to kill off Screenshot Captor plus some other apps and even use a move utility to delete the files, but after all that it hasn't helped. I'm guessing it might work for other situations. The "handle.exe" program (NirSoft?) came in handy or Process Explorer/Hacker would also allow you to determine which processes have the files open.

At least in my case Explorer DOESN'T have the issue and displays all thumbnails, it is ONLY ScreenShotCaptor with the issue.

After reboot today the problem is back...

Sorry for misleading you.

Fribytare · « **Reply #10 on:** October 13, 2021, 06:23 AM »

I tried the portable version and the problem is there too.

mouser · « **Reply #11 on:** October 15, 2021, 08:03 AM »

How strange.. I think it must be something with the windows thumbnail cache. Does anyone know a good tool to tell windows to recover from a problem caching thumbnails in windows explorer?

My latest test was to "Restore defaults" in File Explorer Options - View. Still working after a couple of reboots. So far so good.

Hi, I have just changed View\Extra large icons on folder holding screen shoots. Thumbnails have appeared in SC, after reboot thumbnails are still visible.
Occasionally adjusting slider in SC between list of captured image and preview is required to show thumbnails if they are too big to be loaded.

It still works. But I'm angry because I was so tired that I forgot to compare the settings before and after the reset. Very few settings have anything to do with the thumbs.

dbareis · « **Reply #15 on:** October 17, 2021, 10:15 PM »

As I said earlier, everything points to this being a ScreenShot Captor and not a Windows issue and now I have more evidence.

I renamed an image (with missing thumbnail) "xxxx" (F5=Refresh didn't do anything) went into "View", clicked on "Simple List on Left" and then back on thumbnail, and it now shows the thumbnail (now that doesn't always do it but the fact that it ever did it shows Windows is not the issue).

Other than that is there any log files we can look at?

"ScreenshotCaptor.ini" if backed up (or one of the others, not sure) will have it. I record my settings (at least the important ones) in Evernote.

Fribytare · « **Reply #17 on:** October 18, 2021, 09:41 AM »

Now it doesn't work anymore but I don't know why or since when. This makes me so confused. Old png-thumbs were still there, but I got no new ones. I cleared the thumbs cache in windows and now I can't even get the old ones showing in Screenshot Captor. Of course, I can use jpg but I don't want to.

Btw, I can't find a ScreenshotCaptor.ini on my hd.

This is also happening to me. I doubt it's an SC problem, as I haven't changed anything in the application. However, I have installed a few Windows updates (still on Windows 7). This also happened to coincide with a recent Dopus update, I believe. But I suspect the Windows updates.

dbareis · « **Reply #19 on:** October 18, 2021, 06:41 PM »

I have it installed portable and the "ini" files are in its root directory.

I also haven't changed the app and it is probably a Windows Update which triggered this, but Explorer works, I have no thumbnail issues there, just because something else triggers a bug doesn't mean that the-something-else is where the bug is.

I am on WIN 10 (latest updates)

It happens exactly the same. Maybe some way that Screencaptor has to process the thumbnails has become obsolete and now it no longer works well. I suppose they will have to take the reins and update the program to make it functional again. Meanwhile it is ungrateful to use it.

dr_andus · « **Reply #22 on:** October 21, 2021, 07:54 AM »

If this helps, for me it was between 2nd October and 4th October that the change has occured (or at least those are the dates on the files, the change may have happened earlier).

Looking at my Windows Update history, the only updates I had (on Win7) around those dates were "Security Intelligence Update for Microsoft Security Essentials".

Earlier and later in the month I also had "Windows Malicious Software Removal Tool x64" updates.

Apart from the Dopus update I had, the only other software change I recall was updating the Google Drive sync tool (whatever it's called).

Jesper Hertel · « **Reply #23 on:** March 31, 2022, 07:49 AM »

I have the same problem. The thumbnails only refresh if I open the screenshot folder in Windows Explorer. Then they immediately update in Windows Explorer, and then the updated thumbnails are there again in Screenshot Captor after pressing F5 in Screenshot Captor to refresh. But Screenshot Captor cannot "itself" any longer make thumbnails when taking new screenshots.

That's a pretty big problem, as the thumbnails are quite important for navigation.

I'm using Windows 10 Home (10.0.19043, i.e. 21H1).

Did anyone find a permanent solution that doesn't involve resetting all settings, including settings that have nothing to do with this?

I did install Google Drive recently – could that be the culprit? I don't remember if the problem started at that point, but it could be, since I just remember installing Google Drive during the last 4-6 months and also that the problem with Screenshot Captor appeared within the same time frame. It could also be unrelated.

Hello,

I am currently using jpg instead of png. With the jpg if the thumbnails go
