Before uploading a picture to a photo hosting web site, change its size so that it is no larger than 950 pixels wide.
I am not a Imgur member but they might have a method of changing the picture when you upload it or after it is uploaded. Check it out.
If they don't have a feature that allows changing the picture size you might want to get a Photo Editing program on your computer.
Photoshop is good but it costs an arm and a leg.
There are others that are pretty good that you can download for free. Just be sure to check the web to see how other people liked the free program before you download it.
Some of these are rather poor, some good and some of them are just bait to get you to download Trojans into your computer.
If a lot of other people like the program your thinking of downloading you can be pretty sure it is not a Trojan or Spy material.
"GIMP" is supposed to be good.
"Paint.net" is less complicated than GIMP and is all you need to change your picture size.
I always reduce my picture sizes before uploading them onto a Photo storage site and to keep the original as it was stored, I change the name of my modified picture so it know it is the one I want to show on the web.
I do this by choosing the "SAVE AS" option after I've made the changes and then add the word WEB to the end of the pictures name, right before the ".jpg" suffix.
For instance a picture that ends with,
"crazy aunt.jpg" will end as "crazy aunt WEB.jpg"
Doing this won't effect your original because the name was changed.
While your changing things, it's also nice to reduce the "resolution" from whatever it is (like 200dpi) to something like 80dpi.
On a computer screen, this reduction in resolution won't be noticed and by reducing the resolution it reduces the file size.
Changing both the picture size (pixels) and resolution (200 dpi to 80 dpi) you will GREATLY reduce the file size.
When I say greatly, I'm talking about reducing the picture file size from 20 million bits to 60 or 70 thousand bits.
That allows you to upload more pictures to your web storage and more importantly, it makes the picture on our forum load much faster.
This is a good thing for those people who are still running very slow connections.
