Left thumb shows as expected, but the two on the right when you click on it, stretche into a larger images showing the thumb with bad resolution.

I have been able to get custom thumbs with no problem, but this two puzzle me.
Can you please suggest a solution?

I have done these 2 Thumbs uploads 3 times and I still get the same bad results.

Hmm, definitely an odd problem.  What are the dimensions of the two images causing you problems?

[Nibbler]

That is the true size of the thumbnail image you have created

Sorry, I just realized what has happened...
I started to create a Thumb_nail with a picture that it was already to small, hence the pixelation.

Pilot error.....!!
