Uploading pictures to DHC from your computer doesn't work like this thread shows, anymore.
Now there is no resizing or rotating option, and the site looks for file parameters and just rejects it if you're over.
It then gives you a bogusly worded message with min and max pixel sizes, except they all say "0" except your offending parameter.
It also appears to have a 1M upload limit, and DOES NOT resize things.
Lastly, when you display the page, the pictures that are within the size limits show up inside a window with sliders to scroll around and see the whole image, which is a total pain... you THEN while viewing the page must click each picture ONCE, and it will replace the sliders with full size image.
Basically all iphone and android phones now take pictures waaay to large for upload, you have to open each one in some image editor first and crop, resize, compress to get picture under (I think) 640x480 pixels and 1Meg.
