IQVIA support teams can change/update background images for customer ClinSpark login pages.
There are no image or file size restrictions, however, we have a few recommendations:
Use images in JPG format and 1920x1080 size range
Darker images are usually better
Landscape format imagery feels intuitively better (4x3, 16x9 etc.)
Images that are small (file size in MB and/or pixels) do not look great
Images that are very big (>5 MB) may slow page load times
Images are ‘locked’ at top left, rather than centered in the display. If need/want to display logos or important messages in the artwork, then it is better to have these in the top left quadrant of the image.
