SVG support for image block

[sebastiannberg]

would like to be able to use SVG files directly in the image block when working with the Slack API and Bolt for Java. As SVG is a widely used format for images, supporting this format would enhance the flexibility and usability of the Slack API.

Hi, @sebastiannberg! Thank you for submitting this! 🙇

I attempted to upload an SVG to my Slack workspace and then tried to embed it in Block Kit to see if there was potentially a workaround, but this confirmed that SVGs are currently not supported as you mentioned.

If this was a feature supported by Block Kit, I imagine we could add or extend our SDKs to incorporate that compatibility pretty easily. Unfortunately, since it was confirmed that this is not currently a feature supported by Block Kit, I recommend emailing [email protected] with your request. Doing this will surface your request to the folks at Slack who make the Decisions, which could best influence the addition of the feature. 🙌

Hi @hello-ashleyintech,

Thank you for confirming the limitations regarding SVG support in Slack's Block Kit.

I will follow your suggestion and send a request to [email protected] to bring this to the attention of Slack's decision-makers.

Thanks for your help.
