I don't think I've heard of this problem before, but I'd recommend that you try these two small freeware tools that deal with Explorer context menus and shell extensions:

Hopefully one of those will let you reenable TP's context menu entries!

ThumbsPlus v10 Questions / Thumbsplus items in context menus
« Last post by AndreJS on 2022-04-19 17:59:08 »
I used to have ThumbsPlus items in Windows Explorer context menus (right-click menus). Now they don't appear anymore, despite the option 'show ThumbsPlus items in Explorer right-click menus' is checked.

I've tried to uncheck-apply, check-apply with no success.

Anyone had faced this before?

Will I have to reinstall TP from scratch for this feature come back to work??  :-\

Any suggestion will be welcome! Thank you!

(Win10Pro-20H2)

I just realized, you're also on the Ritlabs forum, aren't you?

Haha, yes I am!

Hopefully someone still looks in this subforum.

I do, but I'm afraid I don't have any suggestions!

ThumbsPlus v7-v9 Questions / Any way to view HEIC in v7

Hopefully someone still looks in this subforum. I recently ended up with a very large batch of HEIC images because I forgot to set the iPhone to use JPG. I'd rather not have to convert all the files, so is there any way to view them in ThumbsPlus v7? Maybe a filter I can associate with it?

Thanks in advance for any help or suggestions!

I don't know the secret recipe either, but the regular thumbnail settings (under Options | Preferences) allow you to choose sharpening and contrast enhancement, so maybe those come into play here as well.

Have you tried if Thumbnail | Export to JPG gives you images of a similar quality?

The Viewer/Editor has an auto-enhancement function in its Image menu that's cryptically named Xe847. One thing that it does is turn anything blueish into a sunny sky blue. Once you know that, it's easy to tell which images have been treated with it. Another possibility could be Histogram stretching.

If you could post a few representative sample images that show the original and web-thumbnailed images for comparison (at the same size), maybe those will offer further clues as to what's happening under the hood.

Hi,

I'm trying to figure out what specific interpolation options, JPEG compression parameters, etc. are used by the Web Page Wizard (Alt+F9) to generate thumbnails. What I'd like to be able to do is set up Batch Process to produce the same images, but so far the specific way Web Page Wizard creates them under the hood eludes me.

This is what I'm setting in the Web Page Wizard - that's all I *can* set as far as JPEG options go. No way to select downsampling interpolation or anything, only size and quality:



This is what I'm using for batch mode:



Source image is a TIFF.

The files end up having the same size in pixels, same basic metadata (quality, resolution, JPEG sampling factor, colorspace, whatever else ImageMagick's "idenfity -verbose" spews out), but they're not the same size in bytes and the resulting image is different, visibly so in some cases. Now, I tried changing interpolation and sub-sampling for batch mode, but it doesn't look like I'm getting the same result anyhow.

Now, you're probably asking "why would anyone want to be that particular about this?" and the answer is, the results we've been getting from the Web Page Wizard's thumbnail generation are so good and reliable for the specific types of images we handle that it's still in use over here long after server-side software became capable of generating its own thumbnails and we stopped actually using the generated webpages themselves - however, this approach is becoming increasingly unwieldy and impractical, for a multitude of reasons you can probably guess yourself. Thus, I've been trying to re-create the Web Page Wizard results in Batch Mode, under the assumption that this is what's actually being used under the hood.

The next step would be to either use Python scripting to integrate that batch flow with an automatic upload to a server - or to use the known set of batch mode options to further re-create the result with ImageMagick, which can be then integrated into server-side software and finally get automatic thumbnails that are not crap within the online store itself.

So, what's the exact magic behind Web Page Wizard's thumbnails? Anyone?

My pleasure, I'm glad it was solved. I've had the same problem myself a few times! :)

Thank you so much!!! You said something that gave me a light! As I had splitted before the main folder in many others to see if I could scan each one entirely, I found there was only one the scan wasn't completing. So I searched where the thumbnails creation was interrupted and 'voilą'!! There was an '.mpg' file lost in the middle of all genuine jpgs ones. By removing it I could complete the thumbnails scan. Thank you for your valuable help! Best regards!
