What is the size limits for embedded images in IBM Connections?

Thomas Hampel

IBM Connections Cloud is offering a wooping 1 TByte of personal file storage and 50 Gbyte of storage for each community.
What you might not be aware of is that there is another limit which apply when embedded images.

While the industry is talking about 4k-UltraHD displays with 8 megapixels, the standard computer display these days doesnt have more than a FullHD display ( 1920x1080 pixel ) with 2 megapixels.
I stumbled into those limits when working with a really large JPG file: in my case it was an image with 96 mega pixels (=190 Mbyte, 17384px x 5558px)
A typical JPG image with 4k resolution should have a size of about 10 Mbyte, so its a little odd to complain about not being able to embed a 96 mega pixel image.

There is no limit on height/width, just an overall size limit for each embedded image which unfortunately is not consistent across the different connections applications.

However... here are the limitations for embedding images in the various connections components:
IBM Connections Cloud (S1 / S2)
Files (Personal) 2 Gbyte per file, 1 Tbyte in total
Files (Community) 2 Gbyte per file, 50 Gbyte in total
Activities 2 Gbyte per file
Wiki 75 Mbyte per image
Blog 10 Mbyte per image
Forum 30 MByte per image
Homepage/Status 10 Mbyte per image
Profile 5 Mbyte for profile photo.




Please note that instead of embedding an image, it is always possible to link a link to your personal file store instead which allows linking extra-extra-large images of up to 2Gbyte in size.

WIKI's

In an onprem environment the max. size in MB is part of the error message

It is possible to modify these limits by editing the wikis-config.xml

or by setting higher defaults for size limits as described by Rainer Brandl

In Connections Cloud the limit is predefined by IBM and can not be changed by customers.
Also the error message in Connections Cloud is a little misleading:

Note: A bug report has already been created, so I assume its fixed soon.

Forum, Blog, Ideation Blog

For a Forum post, blog post or ideation blog entry the error message is misleading in Connections Cloud as well as for OnPrem deployments as it indicates a damaged file or virus infection.

Of course the file is not virus infected nor damaged.

In onprem deployments the default limit of 1Mbyte can be customized in the files-config.xml

...and for Connections Cloud a bug report has been created to update this error message with something more meainingful
