Thank you, Evgene!
For anyone else who is interested:
Select your list more properties attribute codedata-filter-reveal/code and value codetrue/code add
bump - also interested if anyone knows how to.
Mine's working fine - Chrome on Windows 7.
So your image is loading the right ID/file name into a label but won't show when mapped to an asset?
What javascript have you added to the mapped items? Is it appending the filename with the URL of the filesystem?
i.e.: ../files/views/assets/image/[filename].jpg
If you manage to fix this issue I will be interested in knowing what optimisations you have made in general, as I'm also looking to increase speed of transitions between pages etc.
Have you tried changing the format (jpg,png etc.) of the images or checking if they are all the same?
Also flickering can sometimes occur if the page is loading something out of the container. Have you tried adding codeoverflow:hidden/code to the css class?
