We have been modifying the UI of the portal . After updating the portal version to 220.127.116.11 the images started not being fetched properly.
After checking the network tab of chrome developer console, we saw that the website was fetching only 50%, sometimes less than 50% depending on the size of the image.
Release : 5.0.2
Component : API PORTAL
There is 64kb size limit for PNG pictures in the custom pages.
you workaround this by splitting up the image in several parts to prevent quality reduction for larger images.
custom pages are depreciated in portal 5.0.2
