I think he is more concerned about getting into the actual post.
But you bring up a great point, as PDF is required to place a gear list in your profile. Also if you have Adobe Acrobat, you can save a PDF as a JPG file, but is loses a lot of its resolution.
Another little tid bit, if you copy a selection in Excel and paste into another application, such as Word or Power Point, you want to use "Paste Special..." and select one of the picture formats. Much better resolution and bitmaps work best. If you just paste it, the actual spreadsheet is copied, although you can only see the selection. However if you double click the "picture," the actual spreadsheet will open. Not sure if this is true in the newer version of MS Office.
Several years ago during a performance review, my boss built a Power Point for each of his managers, with a screen shot of payroll information for the individual employee. I double-clicked it and it contained all the data for all the managers in several worksheets in the imbedded workbook. Enabled me to negotiate a significant raise :)
