We have a dashboard of campaigns' performance(Tableau Desktop 9.3) --> every campaign has a picture(custom shape) in tableau repository/Shapes/campaign pics.
Pictures were both png and jpeg. They added significant size to dashboard: with pics 13 Mb, without pics 2 Mb
I changed all pictures to jpeg(5-10 Kb each) and created a new folder in Shapes
When I tried to change couple of pictures to new ones from new folder, size of the dashboard increases dramatically.(20 Mb)(size of pictures 5-10 Kb, increase of size is in Mb).
I tried to make reset of all pics----> size is back to 2 Mb ----> then after adding 4-5 pics from new folder(10 kb each) size is 10 Mb ----> couple of more pictures 16 Mb.
Btw, Size of new folder is 3 Mb
I have no idea why it is happening, and I guess the problem description is not so clear, so I can provide any further details. Unfortunately I can not use db here or protect it.
Thanks in advance for your help!
What version of Tableau are you utilizing? I'd like to reproduce the issue but just need a few more details.
