Number of images in display loop

I am using the Content Source : "Folder with Images".

I have 6 images in the folder specified. But can only get 5 of the 6 images
to display in the rotation.

Based on the testing I have done, this appears to be a hard coded value.
Is this something I can change somewhere, or am I missing something in the user interface?

Thanks all

Check image that is not displayed.Move it from there temporally and copy some of others with new name.

If I rename that last image so that it appears as the first file displayed
in the carousel, and it displays just fine.
all the images are 1366w x 456h and under 256k in size.

I have deleted all thumbnail images, and refreshed the page, still with no luck.

Though I think the rename I did above accomplishes the same thing that you are suggesting, I will do as you suggested.

Ok, so I deleted the last image that was not displaying.

Added 3 others, for a total of 8 images in the folder monitored by the
carousel.

It displayed 7 of the 8 images.

If I delete image number 7 of the 8 images, (a total of 7 images in the folder now), it will show 6 of the 7 images.

If I rename image 7 so that it shows up as the first image in the "loop"
it will now display that image, and the 5 others (still a total of 6 images).
But will not show image 7, (which was originally one of the first 6 that displayed)

Thinking through this logically, it almost appears as though the code is set to do a count, then -1 instead of a count +1, or something like that.
Thanks

No it's not the code. You can check:
modules\mod_hot_joomla_carousel_pro\tmpl\default.php

That problem occurs occasionally here and there. Can you put some dummy text in first line of image links box.

I put the text dummytexthere in the first line of "Image Links" text box
No difference

Then I cleaned up all cache, and purged all expired cache, and tried again.
No difference.
