We are using the SSRS 2012 [ExportOpenXML].
When a report is export to excel, getting the message Unknow Image Format IMage/GIF.
Please suggest a fix the above issue.
As per article Excel Rendering extension: Unknow Image Format image/x-png suggestion verified in Visual studio selected the gif file in the Solution Explorer panel, checked the Properties the MIME Type which is already set as image/gif.
Note: Dev environment its working as expected and but issue is observed in QA environment. I wonder some setting is missing on QA enviornment which I'm unable to get the difference exactly.
Quick help would be higly appreciated.
