In my quiz there is an image
http:/ipm-mathemagic.com/new/learning/filter/tex/pix.php/3f0fb0be838a0b57bf7b71ba5eafa50a.gif . this image is displayed properly in moodle or even independently
However I have built an ionic app to show the quiz on android device . There ionic does not seem to load this image . However all other static images on server are shown properly . So what is specific about these images which are created at runtime ( by latex or images those I uploaded in questions ) .
Also all images are shown properly when I run app on desktop using ionic serve , its only device it has issues.
Let me know if anyone faced this issue
