Resize image attachments in pop ups

[JoannaGarland]

Hi! 

I have been searching for an answer online to this, but I can't seem to find help! I am currently adding images as attachments to a feature class. However, when I click on the pop-up, the attachment images are very small. Is there a way to change the viewing size of the attachment image within the pop up?

Many thanks!

In ArcGIS Pro, there isn’t a setting to increase the attachment thumbnail size inside the pop-up’s Attachments element. Attachments are shown as thumbnails; to view them larger you need to click the thumbnail/link to open the attachment in the default viewer.
