Refresh of Images used in a Confluence Page when the source changes on BOX/sharepoint

[UdayKiran]

I'm working to build charts that show various trendlines for the projects.

The script i use can generate .png images of the trend lines (working on enhacing the script to write them to BOX/SharePoint)

I would like to put these images on a confluence page (for the ease of showing it to everyone).

My problem : I've used image macro to load image from BOX/Sharepoint. Where there is a change to the original image, the change is not getting reflected on Confluence Page even after reloading the Confluence Page.

Is there a way to have the images updated when the source changes (of course, with an refresh on Confluence Page)?

I guess the macro is caching external images... :-?

Just a quick idea: how about attaching your chart images to the Confluence page. Every time when the charts are updated, you just attach the new version. If you display the attachment in the page, it will reflect the latest version automatically.

It may require some programming work, so it may not suitable for you.
