Since a few updates back, the final URL path shown after clicking on the image shows:

"https://www.mywebpage.com/PublicImageNew/zp-core/full-image.php?a=Ebay&i=IMG_0300.jpeg&q=75&wmk=%21&dsp=protected&check=06f68772c1bb431b82a64867bf87887ef0ae4b20"

but not the direct link to the location of the file:

"https://www.mywebpage.com/PublicImageNew/albums/Ebay/IMG_0300.jpeg"

I am not sure how to correct this. Can someone advise what I should do? Thank you very much.

That is the protected full image url. Please see Options > Image for related settings.
