    Confluence produces a stacktrace error com.atlassian.confluence.importexport.ImportExportException when we display a big png dimension image with align parameter. In order to reproduce the problem, please go through the following steps: # Create a page containing the following: {noformat} h1. !RAP-Configuration-ERM.png|align=center! {noformat} # Save it # Export the page to PDF. If you, either remove {{align=center}} or h1, the export function will be working fine. The following is the stacktrace that happens after exporting the page to PDF. {noformat} com.atlassian.confluence.importexport.ImportExportException: org.apache.velocity.exception.MethodInvocationException: Invocation of method 'exportWikiToXslFo' in class com.atlassian.confluence.importexport.impl.WikiExporter threw exception com.atlassian.confluence.renderer.WikiRenderException: Error while generating XSL-FO for 'EAIPROJECTS:Configuration Database' @ com/atlassian/confluence/pages/Page.pdfexport.vm[20,37] at com.atlassian.confluence.importexport.impl.PdfExporter.generateXslFo(PdfExporter.java:165) caused by: org.apache.velocity.exception.MethodInvocationException: Invocation of method 'exportWikiToXslFo' in class com.atlassian.confluence.importexport.impl.WikiExporter threw exception com.atlassian.confluence.renderer.WikiRenderException: Error while generating XSL-FO for 'EAIPROJECTS:Configuration Database' @ com/atlassian/confluence/pages/Page.pdfexport.vm[20,37] at org.apache.velocity.runtime.parser.node.ASTMethod.execute(ASTMethod.java:286) caused by: com.atlassian.confluence.renderer.WikiRenderException: Error while generating XSL-FO for 'EAIPROJECTS:Configuration Database' at com.atlassian.confluence.importexport.impl.WikiExporter.exportWikiToXslFo(WikiExporter.java:106) caused by: com.atlassian.confluence.renderer.WikiRenderException: Can not transform XHTML to XSL-FO due to an error in the following XHTML null at com.atlassian.confluence.importexport.impl.WikiExporter.convertXHtmlToXslFo(WikiExporter.java:205) caused by: java.lang.NullPointerException at org.dom4j.io.DOMReader.read(DOMReader.java:86) {noformat} Please note that I have tried the problem using images which type png, jpeg and bmp.
