Version 1.x and 2.0 of ThermaCam Quickview can not generate multipage PDF reports, only one page at a time.
From Version 2.1, you can generate PDF reports of several pages. When you are finished adjusting and analysing the images, switch to Thumbnail (Gallery) view, mark the images that you want in the Report. Then Drag-Drop the images onto the Report Pages area and click "Create Report". A preview of the report is displayed. The final step is to click "Save as PDF".
