imagetwist.com images not showing up

[Curmudgeon]

Something has changed in the last couple of days so that I can no longer see imagetwist.com final images, but I don't know where the problem lies. Here's the response when I click on any imagetwist thumbnail using Firefox:

Content Encoding Error

An error occurred during a connection to imagetwist.com.

Please contact the website owners to inform them of this problem.

With Microsoft Edge or Google Chrome I don't get an error message; instead I get a new tab that has zero content instead of the expected final image. Clicking on thumbnails from other image hosts works as expected in all browsers, and I can see the thumbnails served up by img400.imagetwist.com. Disabling my Bitdefender antivirus doesn't fix the problem.

Anybody have a clue?

I just had a problem on my iPad, with imagetwist?

The thumbs show ok, but when I click on a picture all I get is a webcam advertisement, with no way out to see the picture.
I tried several images, all with the same result?

Now, back on the PC, they are ok. Something is going on with them!

I did nothing to my PC and now imagetwist images are showing up again. I have to infer that the problem's not on my end. So I'm happy, but perplexed.

I still can't see images on the iPad, but can on the PC. It must be a change to their advertising?
