You have to get that picture bigger. The forum can handle 200kb pictures which are about 10 times the dimensions of the picture you posted.
When re-sizing pictures, I just open the original in Paint, then hit the resize button and reduce dimensions to about 25%, hit save and check the file size. If it's over 200, I hit undo and reduce a little more. If it's way under 200, I hit undo and reduce to something like 30%. A couple of tries and it get's it to right about 190kb.
I can see why you might be a little gun shy, but unless the color is a deeper purple than a "sun colored amethyst" or an ugly brown (definitely NOT amber), it's probably not nuked. Both these jars you're asking about are natural colors. If I were you, I'd be more concerned about NEW jars passed off by some unscrupulous dealer as being OLD, and "heat-stained" or color altered - that's painted on the inside in a transparent coating that may appear to be a color. see: http://www.ebay.com/itm/Purple-BALL-MASON-WIDEMOUTH-SQUATTY-HALF-PINT-FRUIT-JAR-VTG-ZINC-LID-/200969686732?pt=LH_DefaultDomain_0&hash=item2ecaba0ecc
