I use Apple's Aperture to manage my photos. I need to export from Aperture to upload here. I have several options for export size. I just uploaded 4 images of Plant: (Quercus macranthera).

You can tell by the time which one was uploaded first... 1st one at 50% - 2nd at constrain to 640x640 and the 3rd one is constrain to 1024 x 1024, the last one I did a custom setting and have it at 800x800 pixels.

The last one, that is 800x800 was uploaded at 9:05 p.m. It looks the best to me.

Would someone mind checking it and see that they can see the entire image on their PC before I upload a bunch of these?

Thanks!

800x600 is an excellent size.

Anything up to 1000 pixels is good. Anything above that, and the system will automatically resize it down for you.

Thanks Dave! Sue deleted the ones with the larger images. I will use the 800 size!
