I know it's going off subject a bit, but I've got to ask - Chris's pictures are smaller in KB but bigger - how is that done - what am i missing - are they compressed or something?
Yes, the image is "compressed" - also known as "optimised". Basically, any digital image can be "optimised" to reduce the amount of detail in the picture and therefore also get a lower Kb size, but still leave it looking good enough for screen display.
This is also called "Quality level" in many photo editing routines and there is usually a simple "High / Medium / Low" setting for "quality". So, an image of say, 600 x 400 pixels (width and height) could be set to High quality and give a Kb size of, say, 1Mb. If the same image was set to Medium quality its Kb size could be, say, 400Kb or if set to Low quality it could be something like 100Kb.
By experimenting with both "Resizing" and "Image Quality" settings a photo can be made visibly acceptable with quite large width and height, but with Kb size that easily fits the Board limit.
