Hi @LauraHenderson - if you hover over your image (and other images you’ve posted) you’ll notice that instead of a descriptive ALT tag (which is very useful for those with vision disabilities and automated systems trying to discern a context for these images), it actually says “MicrosoftTeams-image”. So, not only is Microsoft not alerting you to the option of including a descriptive ALT tag (which is best practice, and would be the “right thing” for Microsoft to do), instead it’s actually using the ALT tag functionality as an insidious branding/marketing opportunity for its proprietary (closed) products. Just another example of the way Microsoft (and other big tech megacorps) impose taxes on us all.
If you want to swap in a descriptive ALT tag, see the instructions @cogdog left in another topic (tl;dr - just edit your posts and replace “MicrosoftTeams-image” with your own caption between the [] and before the | if there is one.)
